摘要
方法基于季铵型强碱性阴离子交换树脂在６─１０ｍｏｌ／Ｌ盐酸介质中强吸附铁面铕完全不被吸附，达到铁与铕分离。吸附在树脂上的铁用水解吸。微量铁在三乙醇胺─乙二胺─氢氧化销体系中测定，铁的峰电位为─１．０８Ｖ（ｖｓ．ＳＣＥ），铁的浓度在０．０５—１０ｎｇ／ｍＬ范围内呈良好的线性关系，可定量测定。
new method is described for europium separation from micro iron with anion-exchange resin 201 × 7 in (1 + 1 ) hydrochloric acid. In supporting electrolyte triethanolamine ethylenediamine-sodium hydroxide, a sensitive wave appeared with peak potential-1. 08V (vs. SCE). The height of wave was rectilinearly related to the concentration of Fe(Ⅲ) in the range of 0. 05 to 10μg/mL.
