摘要
本文对EHEHPA(即P_(507))萃取Cu(Ⅱ)的平衡做了一些研究,测得了萃合物的络合比,确知萃合物的组成为CuA_2·H_2A_2,并测得了室温下(298k)的萃取平衡常数k值在3×10^(-5)~8×10^(-5)之间。萃取平衡方程为: Cu^(2+)
In this article,we probe into the equilibrium of the extraction of Cu( Ⅱ) by using P507, measurs the complex rate of extraction compound(its composition is CuA2-H2A2) and its equilibrium constant k(b. t. 3×10-5and 8×10-5)under normal atmospheric temperature ( 25℃),and come to the coclusion that its equilibrium equation is :Cu2++2H2A2 = 2H++CuA2· H2A2
