甲基膦酸二甲庚脂(P350)在萃取柱色层法中用作固定相分离富集微量金属离子的工作,近几年已有许多报道,但迄今未见用于微量铁的分离富集工作。本文提出了一个用4.0mol/L盐酸为流动相(分析纯浓盐酸通过P350色层柱纯化后使用,下称纯盐酸),以P350为固定相,硅胶为载体的萃取柱色层分离微量铁的方法。研究了分离条件、柱容量和干扰等。样品考核结果满意。

In recent years, many studies have been reported on the separation and enrichment of trace metal ions used as the stationary phase in the extraction of column hemi-methyl methyl fumarate (P350). However, up to now, no separation of trace amounts of iron has been reported Set work. In this paper, a new method was developed for the separation of trace Fe (superscript 2+) with 4.0 mol / L hydrochloric acid as the mobile phase (pure hydrochloric acid purified by P350 chromatography column, hereinafter referred to as pure hydrochloric acid) and P350 as the stationary phase. Methods. The separation conditions, column capacity and interference were investigated. Satisfaction with the sample test results.
