Study on Extraction and Purification Processes of Precious Metals from Spent Auto-exhaust Catalysts AITranslate
Abstract AITranslate
The object of the study is the spent auto-exhaust catalyst, and its precious metals were recovered by leaching and extraction processes. The results indicate that 80 mL aqua regia has the optimal leaching effects of precious metals by leaching at 80 ℃ for 4 h,with platinum leaching rate of 95.96%. Using tribu-tyl phosphate or trioctylamine as the extractant, extraction effects of leaching solution were studied under different conditions. The results show that the kerosene solution of 10% trioctylamine has the best extrac-tion efficiency for precious metals. Thiourea-hydrochloric acid has low stripping rate from metal-containing extract liquid.
