of time. Among 3 group of rabbits, content of heavy metal of NISE group increases at the highest level, contents of the above 5 elements are 5.6, 8.1, 12.9, 4.7 and 3.8 times higher than those in the blank group, which indicates potential damage to animal’s health after smoking. Key words: inductively coupled plasma-atomic emission spectrometry (ICP-AES); kidney organ; heavy metal 全世界每年有300万人死于与吸烟......
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......
Comparison of heavy metal removal efficiencies infour activated sludge processesYANG Jun(杨军), GAO Ding(高定), CHEN Tong-bin(陈同斌), LEI Mei(雷梅), ZHENG Guo-di(郑国砥), ZHOU Xiao-yong(周小勇)(Center..., Pb and Zn) were investigated in the 17 operating municipal wastewater treatment plants (WWTPs) and compared with those in four main activated sludge processes. Significant differences of heavy metal......

School of Minerals Processing... concentrate, the floatability of quartz with the presence of metal ions was studied using amyl xanthate as collector. The results show that the activation of quartz is one of the main factors......
these polymers in the removal of metal ions in waste and natural water [14]. Most of these studies only investigated the possible uses of chitosan and its derivatives to remove heavy metals. Little work... potentials of adsorption metal ions [2], noble metal ions [3-5], dyes [6-7], proteins [8] and humic acid [9-10]. Several methods have been used to modify raw chitosan flake by either physical or chemical......
