本文选择氨羧络合剂 EDTA 和 KCl 作为铂钯的竞争配体,记录其一阶、二阶导数光谱,利用“零点法”同时测定铂和钯。方法简单、快速、适度混浊不影响测定。
In this paper, ammonia and carboxy complexing agent EDTA and KCl were selected as the competitive ligands for platinum-palladium. The first-order and second-order derivative spectra were recorded. The “zero point method” was used to determine both platinum and palladium. Method is simple, fast, moderate opacity does not affect the determination.
