Selective removal of heavy metal ions in aqueous solutions by sulfide-selector intercalated layered double hydroxide adsorbentJing Wang1,Liang Zhang1,Tianshu Zhang1,Ting Du1,Tao Li2,Tianli... synthesized for selective heavy metal removal.The intercalation of sulfurated groups in the interlayer of the layered double hydroxide(LDH)nanosheets endows NFL-S as a selective heavy metal ion filter......
words: mining activity; heavy metals; contamination; soil pollution; metal form ... process exposes different characteristics. So it is not rational to do the research generally to get information of heavy metal pollution. In this work, a Zn-Pb mine in Hunan Province, China......
Removal of SO42-, uranium and other heavy metal ions from simulated solution by sulfate reducing bacteria WANG Qing-liang(王清良)1, 2, DING De-xin(丁德馨)2, HU E-ming(胡鄂明)2, YU RUN-lan... geochemical environment for groundwater is changed since leachant is injected into the water bearing uranium deposit. This increases the concentration of SO42-, uranium and other heavy metal ions......
Role of Heavy Metal Ions in the Formation of Oxyfluoride Glasses and Glass CeramicsMin Liu1,Lijuan Zhao1,2,Yan Liu1,Zijian Lan1,Lifen Chang1,Yiming Li1,Hua Yu11. The MOE Key Laboratory of Weak Light... of different heavy metal ions on the formation of the oxyfluoride glasses and glass ceramics, samples with different Pb F2/Cd F2 ratios have been prepared by the melting quenching and thermal treatment......
acid is known to be one of the major facilitators of the transport of metal ions in the environment. HA may be strongly adsorbed on soil particle surfaces and could influence the activity of heavy metals in the soil. Several studies have demonstrated that HAs can form stable complexes with many heavy metal ions, thus influencing their extraction efficiencies from soils [10]. Therefore, humic acid......
heavy metals from the contaminated soil. Key words: heavy metal; bioleaching; Penicillium Chrysogenum; organic acid 1 Introduction Soil contamination has become a serious problem with the economy and industry development. Heavy metal soil contamination is more serious than any other soil contamination. Smelting and beneficiation are the main ways of soil heavy metal contamination. Smelting slags......
of lead chloride (PbCl2), copper chloride dihydrate (CuCl2·2H2O) and zinc chloride (ZnCl2) are prepared for using. In this study, the contents of heavy metal ions in soil are chosen as 1000, 5000... and curing time increase. Due to the complex effect of fiber and the existence of heavy metal ions, higher cement content and longer curing time may reduce the brittleness of specimens. The possible reason......
to its electrochemical nature by using anodic intensifiers of heavy metal ions (Pb2+, Bi3+, Tl+, Hg2+ and Ag+) on the basis of hydrogen peroxide assistant leaching on three different types of materials... assistant leaching. For the five tested heavy metal ions, Bi3+and Tl+ presented co-intensifying effect on all the three materials, and Hg2+ caused co-intensifying effect on both refractory and easily......
Influence of heavy metal stress on morphology and physiology of Penicillium chrysogenum during bioleaching processDENG Xin–hui(邓新辉)1, 2, CHAI Li-yuan(柴立元)1, 2, 3, YANG Zhi-hui(杨志辉)1, 2, 3, WANG Yang..., China;3. Chinese National Engineering Research Center for Control & Treatment of Heavy Metal Pollution,Changsha 410083, China)Abstract:In order to improve the efficiency of bioleaching heavy metal......
objective of this work was to investigate the potential adsorption ability of orange peel xanthate for the removal of five heavy metal ions (Cu2+, Cd2+, Pb2+, Zn2+ and Ni2+).2 Experimental 2.1 Chemicals... as adsorption condition for the following experiments. Fig.3 Effect of pH on adsorption of heavy metals on XOP 3.3 Adsorption isotherms Initial mass concentrations of metal ions were varied (50-1 000 mg/L......
