摘要
本文采用离子交换分离,EDTA络合滴定的化学分析方法测定Y-Ba-Cu-O体系中Y、Ba、Cu的组成,其相对误差小于0.5％,本方法准确度高,设备简单、耗时短(约2—3h)。
A rapid, accurate chemical method without sophisticated equipment was developed. After separation by ion-exchange the individual constituents were determined by complexometric titration. The relative error of the method is less than 0. 5%.
