| 1 | Microwave photocatalytic degradation of Rhodamine B using TiO_2 supported on activated carbon:Mechanism implication显示文摘The photocatalytic degradation of Rhodamine B(RhB) was carried out using TiO2 supported on activated carbon(TiO2-AC) under microwave irradiation.Composite catalyst TiO2-AC was prepared and characterized using X-ray diffraction(XRD),transmission electron microscopy(TEM) and Brunauer-Emmett-Teller(BET).In the process of microwave-enhanced photocatalysis(MPC),RhB(30 mg/L) was almost completely decoloured in 10 min,and the mineralization effciency was 96.0% in 20 min.The reaction rate constant of RhB in MPC using TiO2-AC by pseudo first-order reaction kinetics was 4.16 times of that using Degussa P25.Additionally,according to gas chromatography/mass spectrometry(GC/MS) and liquid chromatography/mass spectrometry(LC/MS) identification,the major intermediates of RhB in MPC included two kinds of N-de-ethylation intermediates(N,N-diethyl-N'-ethyl-rhodamine(DER)),oxalic acid,malonic acid,succinic acid,and phthalic acid,maleic acid,3-nitrobenzoic acid,and so on.The degradation of RhB in MPC was mainly attributed to the destruction of the conjugated structure,and then the intermediates transformed to acid molecules which were mineralized to water and carbon dioxide. | HE Zhong,YANG Shaogui,JU Yongming,SUN Cheng State Key Laboratory of Pollution Control and Resource Reuse,School of the Environment,Nanjing University,Nanjing 210093,China. | 2009 | Journal of Environmental Sciences2009，21，2： | 22 |
| 2 | Nitrated and parent PAHs in the surface water of Lake Taihu,China:Occurrence,distribution,source,and human health risk assessment显示文摘Nitrated polycyclic aromatic hydrocarbons(NPAHs)have toxic potentials that are higher than those of their corresponding parent polycyclic aromatic hydrocarbons(PAHs)and thus have received increasing attention in recent years.In this study,the occurrence,distribution,source,and human health risk assessment of 15 NPAHs and 16 PAHs were investigated in the surface water from 20 sampling sites of Lake Taihu during the dry,normal,and flood seasons of 2018.The PAH concentrations ranged from 255 to 7298 ng/L and the NPAH concentrations ranged from not-detected(ND)to 212 ng/L.Among the target analytes,2-nitrofluorene(2-n Flu)was the predominant NPAH,with a detection frequency ranging from 85%to 90%and a maximum concentration of 56.2 ng/L.The three-ringed and four-ringed NPAHs and PAHs comprised the majority of the detected compounds.In terms of seasonal variation,the highest levels of the NPAHs and PAHs were in the dry season and flood season,respectively.Diagnostic ratio analysis indicated that the prime source of NPAHs was direct combustion,whereas in the case of PAHs the contribution was predominantly from a mixed pattern including pollution from unburned petroleum and petroleum combustion.The human health risk of NPAHs and PAHs was evaluated using a lifetime carcinogenic risk assessment model.The carcinogenic risk level of the targets ranged from 2.09×10^(-7)to 5.75×10^(-5)and some surface water samples posed a potential health risk. | Jijie Kong Yuxuan Dai Mengshu Han Huan He Jiapeng Hu Junyi Zhang Junzhe Shi Qiming Xian Shaogui Yang Cheng Sun | 2021 | Journal of Environmental Sciences2021，33，4： | 6 |

| 4 | UV/H2O2 oxidation of tri(2-chloroethyl) phosphate: Intermediate products, degradation pathway and toxicity evaluation显示文摘Tri(2-chloroethyl) phosphate(TCEP) with the initial concentration of 5 mg/L was degraded by UV/H2O2 oxidation process. The removal rate of TCEP in the UV/H2O2 system was 89.1% with the production of Cl-and PO4^3- of 0.23 and 0.64 mg/L. The removal rate of total organic carbon of the reaction was 48.8% and the pH reached 3.3 after the reaction. The oxidative degradation process of TCEP in the UV/H2O2 system obeyed the first order kinetic reaction with the apparent rate constant of 0.0025 min^-1( R^2 = 0.9788). The intermediate products were isolated and identified by gas chromatography-mass spectrometer. The addition reaction of HO · and H2O and the oxidation reaction with H2O2 were found during the degradation pathway of 5 mg/L TCEP in the UV/H2O2 system. For the first time, environment risk was estimated via the 'ecological structure activity relationships' program and acute and chronic toxicity changes of intermediate products were pointed out. The luminescence inhibition rate of photobacterium was used to evaluate the acute toxicity of intermediate products. The results showed that the toxicity of the intermediate products increased with the increase of reaction time, which may be due to the production of chlorine compounds. Some measures should be introduced to the UV/H2O2 system to remove the highly toxic Cl-containing compounds, such as a nanofiltration or reverse osmosis unit. | Qiuyi Ji Huan He Zhanqi Gao Xiaohan Wang Shaogui Yang Cheng Sun Shiyin Li Yong Wang Limin Zhang | 2020 | Journal of Environmental Sciences2020，32，12： | 4 |
| 5 | Preparation of hapten-specific monoclonal antibody for cadmium and its ELISA application to aqueous samples显示文摘High-affinity and specific monoclonal antibodies against cadmium-ethylene diamine tetraacetic acid(EDTA)complex have been produced using the hybridoma technique.A hapten was synthesized and characterized by Fourier Transform Infrared Spectroscopy(FT-IR)and UVVis.Competitive enzyme-linked immunosorbent assay(ELISA)for quantitative detection of cadmium in aqueous sample was developed.The monoclonal antibody with high level of binding affinity for Cd-IEDTA-BSA and high specificity for soluble Cd-EDTA complex showed less than 0.99%cross-reactivity with other 11 metals.The limit of detection was 0.10μg·L^(-1),and the effective linear range was 10^(-1)-10^(3)μg·L^(-1).The intra-and inter-assay coefficient variations were 1.5%-6.3%and 3.2%-7.4%,respectively.The spike recovery in different water samples were between 98.5%and 110.3%.The detection limit of this assay was well below the allowable concentration of cadmium(3μg·L^(-1)),and the working range was wider than that of other methods which showed the range of 2.19-86.38 and 0-10^(3)μg·L^(-1).The competitive ELISA established in this paper was sensitive and accurate in the screening of cadmium in aqueous samples.The results will lay a solid foundation for construction of an immunoassay kit for cadmium. | Huan HE Bo TANG Cheng SUN Shaogui YANG Weijuan ZHENG Zichun HUA | 2011 | Frontiers of Environmental Science & Engineering2011，5，3： | 4 |
| 6 | Integrated petrophysical log characterization for tight carbonate reservoir effectiveness: A case study from the Longgang area, Sichuan Basin, China显示文摘Ultra-low porosity and permeability, inhomogeneous fracture distribution, and complex storage space together make the effectiveness evaluation of tight carbonate reservoirs difficult. Aiming at the carbonate reservoirs of the Da'anzhai Formation in the Longgang area of the Sichuan Basin, based on petrophysical experiments and logging response characteristics, we investigated the storage properties of matrix pores and the characteristics of fracture development to establish a method for the characterization of effectiveness of tight reservoirs. Mercury injection and nuclear magnetic resonance (NMR) experiments show that the conventional relationship between porosity and permeability cannot fully reflect the fluid flow behavior in tight matrix pores. Under reservoir conditions, the tight reservoirs still possess certain storage space and permeability, which are controlled by the characteristic structures of the matrix porosity. The degree of fracture development is crucial to the productivity and quality of tight reservoirs. By combining the fracture development similarity of the same type of reservoirs and the fracture development heterogeneity in the same block, a three-level classification method of fracture development was established on the basis of fracture porosity distribution and its cumulative features. According to the actual production data, based on the effectiveness analysis of the matrix pores and fast inversion of fracture parameters from dual laterolog data, we divided the effective reservoirs into three classes Class I with developed fractures and pores, and high-intermediate productivity; Class II with moderately developed fractures and pores or of fractured type, and intermediate-low productivity; Class III with poorly developed fractures and matrix pores, and extremely low productivity. Accordingly log classification standards were set up. Production data shows that the classification of effective reservoirs is highly consistent with the reservoir productivity level, providing a new approach for the effectiveness evaluation of tight reservoirs. | Deng Shaogui Wang Yang Hu Yunyun Ge Xinmin He Xuquan | 2013 | Petroleum Science2013，10，3： | 3 |
| 7 | The sensitivity of the array resistivity log to mud filtrate invasion and its primary five-parameter inversion for improved oil water recognition显示文摘In order to improve reservoir fluid recognition, the sensitivity of array resistivity response to the difference of the invasion properties in both oil-bearing layers and water layers is analyzed. Then the primary inversion is carried out based on the array resistivity log. The mud invasion process is numerically simulated based on the oil-water flow equation and water convection diffusion equation. The results show that the radial resistivity of a fresh mud-invaded oil-bearing layer presents complex distribution characteristics, such as nonlinear increase, increasing to decreasing and low resistivity annulus, and the resistive invasion profile of a water layer is monotonic. Under specific conditions, array resistivity log can reflect these changes and the array induction log is more sensitive. Nevertheless, due to the effect of factors like large invasion depth, reservoir physical and oil-bearing properties, the measured apparent resistivity may differ greatly from the actual mud filtrate invasion profile in an oil-bearing layer. We proposed a five-parameter formation model to simulate the complex resistivity distribution of fresh mud-invaded formation. Then, based on the principle of non-linear least squares, the measured array resistivity log is used for inversion with the Marquardt method. It is demonstrated that the inverted resistivity is typically non-monotonic in oil-bearing layers and is monotonic in water layers. Processing of some field data shows that this is helpful in achieving efficient reservoir fluid recognition. | Deng Shaogui Sun Qingtao Li Hu Huo Ningning He Xuquan | 2012 | Petroleum Science2012，9，3： | 2 |

| 9 | Occurrence, partition behavior, source and ecological risk assessment of nitro-PAHs in the sediment and water of Taige Canal, China显示文摘Nitrated polycyclic aromatic hydrocarbons(NPAHs)are widespread organic pollutants that possess carcinogenic and mutagenic properties,so they may pose a risk to the environment and human health.In this study,the concentrations of 15 NPAHs and 16 polycyclic aromatic hydrocarbons(PAHs)in 30 surface water samples and 26 sediment samples were measured in 2018 from the Taige Canal,one of the main rivers flowing into Taihu Lake,China.The total NPAH concentrations in water and sediment ranged from 14.7 to 235 ng/L and 22.9 to 96.5 ng/g dw,respectively.9-nitrophenanthrene(nd–76.3 ng/L)was the dominant compound in surface water,while 2+3-nitrofluoranthene(1.73–18.1 ng/g dw)dominated in sediment.Among PAHs,concentration ranging from 1,097 to 2,981 ng/L and 1,089 to 4,489 ng/g dw in surface water and sediment,respectively.There was a strong positive correlation between the log octanol-water partition coefficient(Kow)and log sediment-water partition coefficient due to hydrophobic interaction.The fugacity fraction value increased with the decrease of log Kow,and chrysene was transferred from water into sediment.The residual NPAHs in surface water and sediment of the Taige Canal have partial correlation.Diesel engine and coal combustion emissions were probably the principal sources of NPAHs in surface water and sediment.The results of ecological risk assessment showed that some NPAHs inwater(e.g,1-nitropyrene and 6-nitrochrysene)and sediment(e.g.,2-nitrobiphenyl,5-nitroacenaphthene,9-nitrophenanthrene and 2+3-nitrofluoranthene)had moderate ecological risks,which should be of concern. | Jijie Kong Tao Ma Xiaoyu Cao Weidi Li Fengxiao Zhu Huan He Cheng Sun Shaogui Yang Shiyin Li Qiming Xian | 2023 | Journal of Environmental Sciences2023，，2： | 1 |

| 12 | Enhanced degradation of organic contaminants by Fe(Ⅲ)/peroxymonosulfate process with L-cysteine显示文摘The difficulty in Fe(Ⅲ)/Fe(Ⅱ) conversion in the Fe(Ⅲ)/peroxymonosulfate(PMS) process limits its efficiency and application.Herein,L-cysteine(Cys),a green natural organic ligand with reducing capability,was innovatively introduced into Fe(Ⅲ)/PMS to construct an excellent Cys/Fe(Ⅲ)/PMS process.The Cys/Fe(Ⅲ)/PMS process,at room temperature,can degrade a variety of organic contaminants,including dyes,phenolic compounds,and pharmaceuticals.In subsequent experiments with acid orange 7(A07),the AO7 degradation efficiency followed pseudo-first-order kinetic which exhibited an initial 'fast stage' and a second 'slow stage'.The rate constant values ranged depending on the initial Cys,Fe(Ⅲ),PMS,and AO7 concentrations,reaction temperature,and pH values.In addition,the presence of Cl^(-),NO_(3)^(-),and SO_(4)^(2-) had negligible impact while HCO_(3)^(-) and humic acid inhibited the degradation of AO7.Furthermore,radical scavenger experiments and methyl phenyl sulfoxide(PMSO) transformation assay indicated that sulfate radical,hydroxyl radical,and ferryl ion(Fe(Ⅳ)) were the dominant reactive species involved in the Cys/Fe(Ⅲ)/PMS process.Finally,based on the results of gas chromatography-mass spectrometry,several AO7 degradation pathways,including N=N cleavage,hydroxylation,and ring opening were proposed.This study provided a new insight to improve the efficiency of Fe(Ⅲ)/PMS process by accelerating Fe(Ⅲ)/Fe(Ⅱ)cycle with Cys. | Chengdu Qi Yanni Wen Yijie Zhao Yinhao Dai Yanping Li Chenmin Xu Shaogui Yang Huan He | 2022 | Chinese Chemical Letters2022，33，4： | 1 |

| 14 | Role of extracellular polymeric substances in resistance to allelochemical stress on Microcystis aeruginsosa and its mechanism显示文摘Using allelochemicals to suppress cyanobacteria growth is a prospective method for its high efficiency and ecological safety.However,the suppression efficiency is affected inevitably by the extracellular polymeric substances(EPS)produced by cyanobacteria,and the knowledge about the roles of EPS in resistance to allelochemical stress is scarce.For the study,two typical anti-cyanobacterial allelochemicals were adopted to investigate the role of EPS in resistance to allelochemical stress on Microcystis aeruginosa.Results show that EPS was crucial in alleviating the toxicity of allelochemicals to algae,especially in stabilizing the metabolism and photosynthetic activity of algal cells.The aggregation rate of algal cells increased with the increase of EPS secretion,which alleviated the stress of allelopathy.Tryptophan proteins and humic acids in EPS provided a binding site for allelochemicals,and the EPS-allelochemicals complex were formed by chemical bonding.This study improved our comprehension of the role of EPS in algal inhibition by allelochemicals. | Li YIN Ying XU Desheng KONG Juan WANG Kaipian SHI Yong ZHANG Huan HE Shaogui YANG Lixiao NI Shiyin LI | 2023 | Journal of Oceanology and Limnology2023，41，6： | 0 |
| 15 | The active ingredients of Huanglian Jiedu Decoction in treating COVID- 19 based on network pharmacology, molecular docking and molecular dynamics simulation显示文摘Objective:To explore the active ingredients of Huanglian Jiedu Decoction(HLJD)for the treatment of COVID-19 and to further verify the combination mode.Methods:The TCMSP database was used to search for HLJD active ingredients and targets.COVID-19 targets were collected from GeneCards,DisGeNET and OMIM databases.Material-active-ingredients-targets(gene)network and targets protein-protein interaction network were constructed using Cytoscape 3.8.0 and the STRING database.GO functional enrichment analysis and KEGG pathway enrichment analysis of core targets were performed using R software.Cytoscape 3.8.0 was used to build“compound-targets-pathways”to predict HLJD mechanisms,and active ingredients were used as ligands to molecularly dock with SARS-CoV-23CL hydrolase,Spike glycoprotein and ACE2.The binding energy was calculated by molecular dynamics simulations and molecular mechanics Poisson-Boltzmann surface area method,and intermolecular interactions and the contribution of each residue to the binding free energy were analyzed.Results:Four medicinal materials,66 compounds and 219 targets were identified.It is found that the Protein-Protein Interaction core network contained 35 HLJD key targets proteins for COVID-19 treatment.705 GO functional enrichment entries(P<0.05)were produced;while KEGG pathway enrichment analysis identified 142 pathways(P<0.05)involving the Tumor Necrosis Factor signaling pathway and Interleukin-17 signaling pathway,etc.The binding energies of Kihadanin A,Palmidin A,Obacunone and Hispidone are much smaller than those of the currently reported clinical drugs with anti-SARS-CoV-2 drugs.The results of the binding energy indicate that van der Waals force is the main driving force for enzyme-substrate combination,whereas the electrostatic interaction and non-polar solvents contribute less.Conclusion:The“multi-component-multi-targets-multi-pathway”synergy of HLJD,which binds to SARSCoV-23CL hydrolase,Spike glycoprotein and ACE2,can act on targets Heat Shock Protein 90 Alpha Family Class A Member 1,Adrenoceptor Beta 2,Checkpoint Kinase 1,Peroxisome Proliferator-Activated Receptor Gamma and Mitogen-activated protein kinase 14 to regulate multiple signal pathways,and it may have a therapeutic effect on COVID-19. | Ping Xie Xiaohan Jin Yuanfa Lai Chunli Hao Huabin Huang Shaogui He Qihua You | 2021 | TMR Modern Herbal Medicine2021，4，1： | 0 |
