Study on Preparation of High-purity Platinum AITranslate
Abstract AITranslate
High-purity platinum was prepared by the combination process of dissolution of crude platinum with aqua regia-oxidation and carrier hydrolysis-ion exchange-NH4 Cl precipitation,and the effects of impu- rity elements removal in each process step were studied. The experimental results show that platinum can be effectively separated from other precious metals and base metals by dissolution of crude platinum with aqua regia, and then oxidation and carrier hydrolysis,ion exchange and precipitation of Pt-containing solution. The obtained purified （NH4）2 PtCl6 precursor was calcined and washed,and Pt powder was prepared. Based on GDMS analysis,the impurity content in Pt powder is less than 3 ×10^-6 ,and the purity of platinum is more than 99. 999%.
