(一)前言在若干种离子的混合溶液中,欲不经分离而进行个别离子的氨羧络合滴定,必须控制滴定条件。根据作者提出的酸效应公式,可以计算在混合溶液中,控制酸度滴定个别离子的最高和最低酸度范围。但是,对于氨羧络合物的稳定性相近的一些离子(例如△pK<5时),欲不经分离而进行选择滴定,单 (A) Preface In a mixed solution of a number of ions, to be separated without the ammonia ion complexation of individual ions, titration conditions must be controlled. According to the authors proposed acid effect formula, can be calculated in the mixed solution, the acidity and titration of the highest and lowest acidity of individual ions range. However, for some ions with similar stability to the amine carboxylate (for example, when Δ pK <5), selective titration is performed without separation
