提出一种测定天然水中液-固界面三元络合物稳定常数的新方法.其基本原理是基于“S-型曲线左-右摆动规律”,由此得到“交换率E(%)-有机物浓度关系的峰型曲线”,再进一步应用“峰型曲线”分别提出用(1)[H_2A]=[H_2A]_0时E(%)相等法和(2)[H_2A]_(max)极大值法求得(~(?)(SAM)/~(?)(SM))值. 已知~(?)(SM)值后,即可求得液-固界面三元络合物的稳定常数.用两法求得的6个体系的~(?)SAM值很好一致.
A new method to determine the stability constant of liquid-solid interface ternary complex in natural water is proposed.The basic principle is based on the “left-right swing law of S-shaped curve”, and the "exchange rate E (% (1) [H 2 A] = [H 2 A] _0 E (%) Equivalent Method and (2) [H_2A] _ (max) are extremely large when the peak shape curve is further applied. The value of ~ (?) (SAM) / ~ (?) (SM) is obtained by the value method.After the ~ (?) Value is known, the stability of the ternary complex at the liquid- The values of ~ (?) SAM for the six systems obtained by the two methods are in good agreement.
