【Abstract】 A solvent extraction process was used in stead of the currently used metalreduction and precipitation methods for recovery of Pt from spent catalyst. The Pt recovery was higher than 99.9% and was ordinarily maintained around 99%. A commercially applicable process was recommended on the basis of the technological research.更多还原
