摘要
本文研究了在黄河水体中,表面沉积物与铜、铅、锌在液—固界面的作用,绘出了各离子与固体粒子界面作用的离子交换率(E%)—pH曲线。铜铅锌均以一价络离子形式在固体粒子上进行阳离子交换;固体粒子对三种离子亲合性大小顺序为:Pb>Cu>Zn;在天然PH下(8.0~8.5),固体粒子对三种离子的交换率:Pb是100%,Cu是99~100%,Zn是80~100%
Abstract This paper studied the curve of ion exchange ratio(E%)-pH
of the interaction between solid particles with heavy metal CuPbZn in the yellow river, When pH of
the solution changes between 110, Copper,Lead and Zine in monobasic ligand forms exchange
with cations on the solid particles. The exchange ratios of three heavy metals are that Copper is
99-100%, lead is 100%, Zine is 80-100% in the affinity sequence of solid particles with three heavy
metals from big to littel is Pb>Cu>Zn.
