粗铂中钯的分离方法

Study on separation of palladium from polyxene

粗铂经王水溶解 ,赶硝 ,加入丁二酮肟使大部分钯以沉淀的形式与铂分离 ,余留的少量钯用溴酸钠水解法处理 ,可达到铂钯分离的目的 ,所得纯铂品位高于 99.95 %。

Palladium can be separated from polyxene by the process of resolving polyxene,removing nitrate,precipitating palladium,etc.The grade of pure platinum obtained from the process is more than 99.95%.
