P350-HBr体系萃取色层分离铊及测定

EXTRACTION CHROMATOGRAPHY OF TI (Ⅲ) P350—HBrSYSTEM

本文对以P350作为固定相,用萃取色层法从其它基体中分离微量铊的可行性进行了研究。用制定的方法对铜矿、铅锌矿和电转尘中微量铊进行了分离和测定,均获得良好结果。

The purpose of this paper is to study the conditions for estractions chromatogrophy of thallium, the composition of complex compound and separating microamoun ts of thallium, P350aS a stationary phase in extraction, in conjunction With R odamine B method, the produce can be use far determination of thallium in crude copper, iead-2inc cover ter dust with good results.
