铂与贱金属元素分离的方法很多。有利用铂族金属与其贱金属标准电极电位的差异,选择合适还原剂直接分离,有采用载体水解法分离的等等。经典的方法是:采用加固体氯化铵于铂——贱金属混合液中,使铂呈氯铂酸铵沉淀而与其它杂质分离。我们针对试验原料的性质,试用水合联氨直接还原法和氯铂酸铵还原氧化法来分离提纯铂,并着重探讨了影响铂镍分离的
There are many ways to separate platinum from base metal elements. The use of platinum group metals and its base metal standard electrode potential differences, the choice of a suitable direct separation of the reducing agent, the use of carrier hydrolysis and so on. The classic approach is: Addition of ammonium chloride in platinum - base metal mixture, the platinum was precipitated ammonium chloroplatinate and other impurities separated. We test the nature of the raw materials, trial hydrazine direct reduction and ammonium chloroplatinate reduction oxidation separation and purification of platinum, and focused on the impact of platinum and nickel separation
