| 2 | Adsorption of atrazine by natural organic matter and surfactant dispersed carbon nanotubes显示文摘The aggregation and dispersion behaviors of carbon nanotubes (CNTs) can regulate the environmental spread and fate of CNTs, as well as the organic pollutants adsorbed onto them. In this study, multi-walled carbon nanotubes (MWNTs) and single-walled carbon nanotubes (SWNTs) were surface modified with humic acids from different sources and with surfactants of different ionic types. The dispersion stability of surface modified CNTs was observed by UV-Vis spectrophotometry. The effect of humic acid and surfactant dispersion on the adsorption of atrazine by CNTs was investigated by batch equilibrium experiments. Both humic acid and surfactant could effectively disperse MWNTs, but not SWNTs, into stable suspensions under the studied conditions. Surface modified CNTs had a greatly reduced capacity for adsorption of atrazine. The inhibitory effect of peat humic acid was relatively stronger than that of soil humic acid, but the two surfactants had a similar inhibitory effect on atrazine adsorption by the two CNT types. Increases in surfactant concentration resulted in rapid decreases in the adsorption of atrazine by CNTs when the surfactant concentration was less than 0.5 critical micelle concentration. | Baoyou Shi, Xiaoyan Zhuang, Xiaomin Yan, Jiajuan Lu, Hongxiao Tang State Key Laboratory of Environmental Aquatic Chemistry, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, Beijing 100085, China. | 2010 | Journal of Environmental Sciences2010，22，8： | 7 |
| 3 | In vivo toxicity of nano-C_60 aggregates complex with atrazine to aquatic organisms显示文摘The present study aims at investigating the potential impacts of the nC60 complex with atrazine on the development of Japanese medaka (Oryzias latipes) embryos and chronic toxicity to D. magna. Although exposure to nC60 below 8 mg/L had no effects on the hatching rate of medaka embryos, it increased the deformity of hatched larvae. Moreover, the presence of nC60 significantly increased the hatching time of the embryos exposed to atrazine. 14-day exposure of D. magna to nC60 significantly reduced offspring production even at a concentration as low as 0.5 mg/L. This indicates that nC60 is able to reduce the ability of D. magna to produce offspring, and therefore would have an impact on population. For atrazine, no significant difference in offspring production was observed. The nC60 complex with atrazine was also found to significantly decrease the reproduction of D. magna, which was similar to the result of exposure to nC60. These results suggest that nC60 would have potential risks to aquatic organisms. Therefore, much attention should be paid to their associations with other contaminants for fullerene's risk assessment. | YAN XiaoMin ZHA JinMiao SHI BaoYou WANG DongSheng WANG ZiJian TANG HongXiao | 2010 | Chinese Science Bulletin2010，55，4： | 5 |

| 11 | Dechlorination of 2,4-dichlorophenol by nickel nanoparticles under the acidic conditions显示文摘Metal nanoparticles are effective for remediation of contamination with a range of compounds including chlorinated organics.However,the sorption process of the passivation oxide layers on the metal nanoparticle surfaces may result in incomplete degradation of contaminants.This phenomenon can be prevented by an acidic washing procedure or reaction in an acidic medium.In this paper,nickel nanoparticles manufactured via the carbonyl powder process were analyzed using scanning electron microscopy,transmission electron microscopy,X-ray diffraction and energy-dispersive X-ray spectroscopy.The sorption and degradation of 2,4-dichlorophenol (2,4-DCP) by nickel nanoparticles under acidic conditions was then investigated.Transmission electron microscopy and XRD results showed that the nickel nanoparticles range in size from 10 to 20 nm,and a thin passivation layer of NiO is present on the surface.This oxide layer can be removed by pretreatment washing with acidic solutions.It was indicated that dechlorination was the key reaction pathway for degradation of 2,4-DCP by nickel nanoparticles under acidic conditions.The main degradation products were 4-Chlorophenol,2-Chlorophenol,and Phenol,and among these,Phenol was dominant.The acidic medium promoted degradation by providing an appropriate pH,and H+ may be involved in the reaction.Dechlorination of 2,4-DCP by nickel nanoparticles under the acidic condition follows the second order kinetic model,and the rate constants at 298,306,316 K are 0.02,0.2 and 0.3 (g L h)-1,respectively. | FENG Li GE XiaoPeng LI Yi WANG DongSheng TANG HongXiao | 2011 | Chinese Science Bulletin2011，56，21： | 1 |

| 17 | Heavy metal adsorption on the Le An River sediment —The adsorption model显示文摘In this study,the surface properties and adsorption properties of the Le An River sedi-ment were modelled via surface complexation approach.The model parameters were determinedbased on the data of our potentiometric titration experiments and the metal adsorption experimentswith the Le An River sediment samples.Consequently,the surface complexation models for thenatural sediment,in our case the Le An River sediments,which can interpret the experimental datavery well were successfully established.Three typical surface complexation models that is the con-stant capacitance model,the diffuse layer model and the triple layer model,were considered in thisresearch.This work indicated that the consistency and the interdependency among model parame-ters together with the selection of the surface adsorbed species should be emphasized. | Wen Xianghua Du Oing Tang Hongxiao Research Centre for Eco-Environmental Sciences,Chinese Academy of Sciences.Beijing 100085,China | 1997 | Journal of Environmental Sciences1997，9，1： | 1 |
