摘要

棕壤对铜的吸附特性以及土壤条件对吸附的影响进行了研究，结果表明，棕壤对铜的吸附随溶液中铜的平衡浓度增加而增加，但在高浓度时增幅渐缓，与处于相同地区的褐土相比棕壤的吸附相对较弱，其吸附可用Langmiur、Frundlich、Temkin及米氏方程进行描述。土壤酸度增强，棕壤对铜的吸附降低，用H^＋浓度对Frundlich方程进行修饰，能更好地描述铜的吸附状况。此外，离子强度、陪伴离子对吸附都有影响，随离子强度增加及高价陪伴离子比例的上升吸附减弱。

Abstract

The copper adsorbing properties of brown soil and effects of soil conditions on soil adsorption were studied in this paper. The results showed that copper adsorption of brown soil increased with copper equilibrium concentration

but the increase slowed down at high copper concentration. Its copper adsorbing capacity was much lower than that of cinnamon soil

which was in the same region. The adsorbing properties could be simulated with Langmiur

Frundlich

Temkin and Michaclis Menten models. Soil acidity could decrease soil adsorption of copper

and the Frundlich could simulate the isothermal curve better when modified with hydrogen concentration. Other soil conditions e.g. ionic strength and companion ions all had some influence on copper adsorbing properties of brown soil. With the increase of ionic strength and higher valence companion cations

copper adsorption decreased.
