1Brominated dioxins and furans in a cement kiln co-processing municipal solid waste显示文摘A field study and theoretical calculations were performed to clarify the levels, profiles, and distributions of polybrominated dibenzo-p-dioxins and dibenzofurans(PBDD/Fs) in a cement kiln co-processing solid waste, with a focus on the PBDF formation mechanism.The raw materials contributed greatly to input of PBDD/Fs into the cement kiln. The PBDD/F concentrations in the raw materials were much higher than those in particle samples from different process stages in the cement kiln. The PBDD/F concentrations in the clinkers were1.40% of the concentrations in the raw materials, which indicated that the high destruction efficiencies for PBDD/Fs by cement kiln. PBDD/F distribution patterns in particle samples collected from different process stages indicated the cement kiln backend was a major site for PBDD/F formation. PBDFs with high levels of halogenation, such as heptabrominated furans(Hp BDF), were the dominant contributors to the total PBDD/F concentrations and accounted for 42%–73% of the total PBDD/F concentrations in the particle samples. Our results showed that co-processing of municipal solid waste in a cement kiln may influence the congener profile of PBDD/Fs, especially for the higher halogenated PBDD fraction. In addition, there were significant correlations between the decabromodiphenyl ether and heptabrominated furan concentrations, which is an indicator of transformation from polybrominated diphenyl ethers to PBDD/Fs. Theoretical calculations were performed and demonstrated that elimination of HBr and Br_2 from polybrominated diphenyl ethers were the dominant formation pathways for PBDD/Fs. These pathways differed from that for polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs).Lili Yang Yuyang Zhao Miwei Shi Minghui Zheng Yang Xu Cui Li Yuanping Yang Linjun Qin Guorui Liu 2019Journal of Environmental Sciences2019,31,5:5

7Enhanced bright green luminescence from GdOF:Ho^(3+) up-conversion phosphor via Yb^(3+) doping显示文摘In this paper,a series of GdOF-based green phosphors doped with Ho^(3+) and Yb^(3+) ions was prepared by a simple co-precipitation method.The crystal structure s and optical prope rties were investigated in detail.The intensity of the emission of GdOF:Yb^(3+),Ho^(3+) phosphors is enhanced by the effective energy transfer from Yb^(3+) to Ho^(3+),and the optimal luminescence is achieved with the Ho^(3+)doping amount of 0.1 mol%as well as Yb^(3+) doping amount of 5 mol%.Tunable UC emission of samples is achieved by adjusting the doping concentration of Ho^(3+) or Yb^(3+).The purity of the green UC emission is further improved by enhancing the excitation pumping power.In addition,logarithmic functions of green,red and nearinfrared radiation intensities were calculated versus logarithmic function of pump power for further study.A possible UC luminescence mechanism between Yb^(3+) and Ho^(3+) is discussed based on powerdependent UC luminescence spectrum and decay lifetimes.These results suggest that GdOF:Yb^(3+),Ho^(3+)phosphors with bright and high-purity green UC emission have potential applications in the fields of bioimaging,display and illumination.Linjun Qin Yue Guo Jing Xu Lixi Wang Qitu Zhang 2024Journal of Rare Earths2024,42,2:0
8Bridging the Energy Benefit and POPs Emission Risk from Waste Incineration显示文摘Incineration has been the globally controversial and concerned method of solid waste disposal.Energy recovery and volume reduction are the benefits from waste incineration,but risk due to release of persistent organic pollutants is the major public concern in the world.In this study,the emission of organic pollutants including dioxins and polychlorinated naphthalenes from solid waste incineration in China was comprehensively evaluated,and a relationship between energy benefit and pollutant emission was firstly established.The results show that production of medical and industrial waste was smaller than that of municipal waste but yielded comparable or even higher emission of dioxins.The energy benefit-to-emission index for organic pollutants(EBEIOP)for evaluation of solid waste management on a local or regional scale was proposed.Significant correlations between net energy benefit and pollutant emission for provinces with higher EBEIOP values were found.Furthermore,higher EBEIOP values were associated with economic factors while lower values were influenced by emission from incineration of medical and industrial waste.We suggest that an EBEIOP value of R60 can serve as a reference for“profitable”solid waste management,assisting decision making during energy benefit and environmental risk assessment.Cui Li Lili Yang Xiaoyun Liu Yuanping Yang Linjun Qin Da Li Guorui Liu 2021The Innovation2021,2,1:0
