| titleOfInvention | Method for preparing high-purity platinum powder from platinum alloy waste |
| abstract | The invention relates to a method for preparing high-purity platinum powder from platinum alloy waste, which comprises the steps of primarily separating platinum from other alloy elements by hydrolysis and carrier hydrolysis, performing ion exchange, adding a precipitator for hydrolysis, performing ion exchange, reducing hydrazine hydrate to remove other impurities, and extracting high-purity platinum with the purity of more than or equal to 99.999 percent. The method has strong universality, can be effectively implemented aiming at most of platinum alloys, and has the advantages of simple operation, environmental friendliness, high process stability, no special requirement on equipment and the like. |
