摘要
运用表面络合模式和原理,研究了黄河表层沉积物的界面特征,确定了零电点、电荷密度、表面吸附位和表面固有常数.用原子吸收分光光度法测定了天然水环境生物膜对铜和镉的吸附作用.
The interface characteristics of the surface sediment in the Yellow River is studied according to the surface complexation approach.The point of zero charge,the surface charge density and the total adsorptive sites, the surface intrinsic constants were established. Adsorption of Cu^(2+) and Cd^(2+) onto natural aquatic biofilms in surface sediment were determined by atomic absorption spectrophotometry.
