摘要

本文介绍了一种处理不同组成的天然土壤对重金属吸附量(E)实验数据的新技术。计算方案基于非齐次方程组，由土壤矿物成分和E值数据编制而成。根据天然土壤(作为悬浮液)对CuSO4·5H2O溶液中Cu2+离子(高达1000 mg/l)的吸附特性的实验数据，编制了这样一个方程组。在CuSO4·5H2O溶液中，对Cu2+离子的吸附性能最高的是方解石和绿泥石，其次是石英和蒙脱石;白云岩和水云母的吸附特性最低。

THE SORPTION CAPACITY OF NATURAL SOILS IN RESPECT OF COPPER IONS (II) FROM SOLUTIONS CuSO4·5H2O

The paper describes a new technique for processing experimental data on sorption capacity (E) of variously composed natural soils in relation to heavy metals in aqueous solutions. The calculation scheme is based on an inhomogeneous system of equations, compiled from the data on mineral composition of soils and the E values. Such a system of equations was compiled for the experimental data on the sorption characteristics of natural soils (as suspensions) with respect to Cu2+ ions (of up to 1000 mg/l) from CuSO4·5H2O solutions. The highest sorption characteristics with respect to Cu2+ ions from solutions of CuSO4·5H2O were associated with uneven-grained aggregates of calcite and chlorite followed by quartz and montmorillonite; dolomite and hydromica had the lowest sorption characteristics.
