中文摘要：

研究了大工山古铜遗址区矿区土壤对铜的吸附特性。结果表明：遗址区土壤对铜的吸附等温线大多为“L”型等温线，即土壤对铜的吸附量随吸附平衡浓度的增大而增加，平衡浓度较低时，土壤对铜的吸附量随平衡浓度的增大而迅速增加，随平衡浓度的逐渐增加，土壤对铜的吸附量增加变慢。土壤对铜的吸附可用Langmuir方程、Freundlich方程和Temkin方程来描述，其中Freundlich方程优于Langmuir方程和Temkin方程。

英文摘要：

The adsorption characteristic of Cu by soils in Dagongshan ancient copper mine sites was studied in this paper. The results showed that the most of mining area soil to copper adsorption isothermal is the ＂L＂ isothermal. The adsorption of copper in soil was increased along with adsorption equilibrium density. When the equilibrium density is low, the adsorption of copper in soil rapidly increases along with equilibrium density. When the equilibrium density gradually increased, the adsorption of copper in soil was slowed down. The adsorption of copper in soil was described by Langmuir equation, Freundlich equation and Temkin equation. The Freundlich equation is more fit for the curve than Langmuir equation and Temkin equation.
