四甲基氯化铵沉淀法分离提纯铂和钯

Separation and Purification of Platinum and Palladium by Tetramethyl Ammonium Chloride Precipitation

采用四甲基氯化铵从含铂、钯的溶液中分离提纯铂和钯。结果表明,采用该工艺分离提纯铂和钯,可得到纯度大于99.95%的海绵铂和海绵钯,且铂、钯的直收率均大于99.8%。工艺过程简单,操作方便,效果好,能够规模化应用于工业化生产。

Platinum and palladium were separated and purified by tetramethyl ammonium chloride precipitation from leaching solution containing platinum and palladium. The results show that platinum and palladium sponge powder were obtained with purity of 99.95% above and recovery rate of 99.8% above were obtained. This process can be applied to a large-scale industrial production with its advantages of simple flowsheet and convenient operation.
