| 1 | Interaction of polyhydroxy fullerenes with ferrihydrite:adsorption and aggregation显示文摘The rapid development of nanoscience and nanotechnology, with thousands types of nanomaterials being produced, will lead to various environmental impacts. Thus,understanding the behaviors and fate of these nanomaterials is essential. This study focused on the interaction between polyhydroxy fullerenes(PHF) and ferrihydrite(Fh), a widespread iron(oxyhydr)oxide nanomineral and geosorbent. Our results showed that PHF were effectively adsorbed by Fh. The adsorption isotherm fitted the D-R model well, with an adsorption capacity of 67.1 mg/g. The adsorption mean free energy of 10.72 k J/mol suggested that PHF were chemisorbed on Fh. An increase in the solution p H and a decrease of the Fh surface zeta potential were observed after the adsorption of PHF on Fh; moreover, increasing initial solution p H led to a reduction of adsorption. The Fourier transform infrared spectra detected a red shift of C–O stretching from 1075 to 1062 cm-1 and a decrease of Fe–O bending, implying the interaction between PHF oxygenic functional groups and Fh surface hydroxyls. On the other hand, PHF affected the aggregation and reactivity of Fh by changing its surface physicochemical properties. Aggregation of PHF and Fh with individual particle sizes increasing from 2 nm to larger than 5 nm was measured by atomic force microscopy. The uniform distribution of C and Fe suggested that the aggregates of Fh were possibly bridged by PHF. Our results indicated that the interaction between PHF and Fh could evidently influence the migration of PHF, as well as the aggregation and reactivity of Fh. | Jing Liu Runliang Zhu Tianyuan Xu Mingwang Laipan Yanping Zhu Qing Zhou Jianxi Zhu Hongping He | 2018 | Journal of Environmental Sciences2018,30,2: | 5 |
| 2 | TiO_2/Schwertmannite nanocomposites as superior co-catalysts in heterogeneous photo-Fenton process显示文摘The heterogeneous photo-Fenton reaction is an effective technique in combating organic contaminants for both soil and water remediation,and extensive studies have focused on enhancing its efficiency and reducing its costs.In this work,we developed novel photoFenton catalysts by simply milling commercially available TiO_2(P25)with Schwertmannite(Sh),a natural iron-oxyhydroxysulfate nanomineral.We expect that the photo-generated electrons from TiO_2could continuously migrate to Sh,which then could enhance the separation of electron-hole pairs on TiO_2and accelerate the reduction of Fe(III)to Fe(II)on Sh,leading to high degradation efficiency of the target organic contaminants.SEM and TEM results showed the distribution of TiO_2on Sh surface for the nanocomposites(TiO_2/Sh).Under simulated sunlight irradiation,the much higher content of Fe(II)was determined on TiO_2/Sh than on Sh via a common method in the iron ore,and the consumption of H_2O_2and the production of·OH were more significant in the TiO_2/Sh system than those in the TiO_2and Sh systems.These results well support our hypothesis that the photo-generated electrons could migrate from TiO_2to Sh on the composites,and can also explain the much higher degradation efficiency of Rhodamine B(RhB)in the TiO_2/Sh system.Besides,TiO_2/Sh had lower Fe dissolution as compared with Sh,and retained high catalytic stability after four repeated cycles.Above merits of the TiO_2/Sh composites,in combining with their simple synthesis method and low-cost property,indicated that they should have promising applications as heterogeneous photo-Fenton catalysts. | Yanping Zhu Chun Zeng Runliang Zhu Yin Xu Xingyan Wang Huijun Zhou Jianxi Zhu Hongping He | 2019 | Journal of Environmental Sciences2019,31,6: | 5 |
| 3 | Simultaneous sorption of aqueous phenanthrene and phosphate onto bentonites modified with AlCl_(3) and CTMAB显示文摘The purpose of this work is to synthesize a new type of bentonite sorbent that can simultaneously remove both organic compounds and phosphate from water.Inorgan-ic-organic bentonites(Al-CTMAB-Bent)were synthesized by modifying bentonites with both AlCl3 and cetyltrimethyl ammonium bromide(CTMAB).Simultaneous sorption of aqueous phenanthrene and phosphate onto Al-CTMAB-Bent was examined.Removal rates of phenanthrene and phosphate from water reached 96.3% and 90.2%,respectively,at their respective initial concentrations of 1 mg/L and 5 mg/L and the added amount of Al-CTMAB-Bent was 1.25 g/L.The residual turbidity of the Al-CTMAB-Bent suspension decreased 81.4% compared to that of organobentonite sus-pension after a 1 h settling time.Thus,inorganic-organic ben-tonite can be used to treat wastewater containing both organic pollutants and phosphate. | ZHU Runliang ZHU Lizhong ZHU Jianxi | 2007 | Frontiers of Environmental Science & Engineering2007,1,1: | 2 |
