【摘要】 本文提出双参数直接逼近法,借助计算机对一组试液进行吸光度测定,即可同时获取二元显色体系的络合物组成、显色剂用量、摩尔吸光系数以及稳定常数等多种重要信息,优于传统方法。该法应用于 Fe(Ⅱ)—邻菲罗啉显色体系,取得了令人满意的结果。文中对有关影响因素进行了初探。更多还原

【Abstract】 A simple and direct iteration method with di-parameter(G and△)is presented for simultaneous obtaining complex molar ratio, color reagent amount,molar absorptivity and stability constant in two-component coloring system by measuring absorptance of one group of solution with the aid of computer.This method is better than traditional one.And it has been successfully applied to Fe(Ⅱ)- O-phenathrolene Hydrate system.Main influential factors were also discussed.更多还原
