三苯基氧化膦浸渍树脂吸附金的性能及其分析应用的研究

Study on Adsorption of Gold With Triphenylphospine Oxide-Impregnated Resins and Its Application

本文以三苯基氧化膦(TPPO)负载在大孔聚苯乙烯-二乙烯苯树脂上制得了 TPPO 浸渍树脂,用 AAS 研究了 HCl 介质中树脂对 Au(Ⅲ)的吸附性能和反应机理。通过动态试验建立了树脂分离富集-AAS 测定矿样中微量金的方法。

Triphenylphospine oxide(TPPO)-impregnated resins were made by loading TPPO on the macroporous copolymers of styrene-divinylbenzene.The adsorption of gold with TPPO-impregnated resins in hydrochloric acid solution and its reaction mechanism were investigated.A method for the separation and pre-concentration of gold in ores with TPPO-impregnated resins and the determination of gold by flame atomic absorption spe- ctrophotometry were established.
