摘要
本文叙述了用离子色谱法测定稀土元素,选用0.002mol/l乙二胺—0.006mol/l柠檬酸为淋洗液,用本所改装的光度检测器,在无梯度淋洗装置条件下,不需预分离共存元素,可测定多种金属材料中镧、铈、镨和钕。
A method for the determination of La, Ce, Pr and Nd in metallic materials by ion chrom-atography has been developed. 2 mmnol/L ethylenediamine- 6 mmol/L citric acid as eluent andHPLC-CS2 separating column were used Modifed spectrophotometer was proved to be one of thebest detector with DBC-Arsenazo as chromognic reagent for spectrometric determination ofrarc earth elements The method is simple and gives satisfactory results without any soparation.
