Abstract

Adsorption Properties of Cu2+,Pb2+,Cd2+,Zn2+in soils,which were from Shuangyashan City in Heilongjiang,tilia in Changbai Mountain,Xingping in Shanxi and Yulong Moutain in Jilin Institute of Chemical Technology,were studied by Oscillation balance method.Meanwhile,initial Contents of heavy metal in solution on the impact of adsorption were also studied.The results showed that the adsorption of heavy metal in soils was different since the metal and soil characteristics were different.Along with the content of Cu2+,Pb2+,Cd2+,Zn2+increasing,adsorption amounts of four kinds of soil to become saturated.Cu2+ adsorption isotherms of tested soils followed Freundlich equation,and the relevance of Heilongjiang'soil was the best;Cd2+ adsorption isotherms of tested soils followed Langmuir equation,and the relevance of Changbai Mountain' soil was the best.The correlation of Freundlich equation of Pb2+ and Zn2+ adsorption isotherms of tested soils was better than the one of Langmuir equation.
