| 摘 要： | 运用界面分级离子/配位子交换原理和方法研究了黄河水中Cu2+，Pb2+与沉积物相互作用的等温线。这类等温线具有1个“拐点”2个“平台”。应用分级离子交换平衡理论导出的等温式，用作图法求出了2种金属离子与沉积物相互作用的平衡常数K1和K2。证明Cu2+，Pb2+在黄河水中与沉积物的交换吸附是分二级进行的。

| Abstract: | The isotherms of the interaction between Cu2+, Pb2+ and the sediments in the Yellow River were studied by the theory and method of interfacial stepwise ion/coordination particle exchange. The isotherms are stepped, formed by two curves combined together with a “plateau” in the middle. The isothermal equation of surface stepwise ion exchange is applied to calculating equilibrium constants K1 and K2of two metal ions by the diagrams. The exchanged adsorption between Cu2+, Pb2+ and the sediments is stepwise in the Yellow River water. |
