| Abstract: | Waste car catalytic converters have high content of platinum group of platinum, palladium, and rhodium. Extraction procedure of palladium from waste ternary catalysts were investigated. The main process were performed as follows, pretreatment, first immersion, aqua regia leaching, nitrate drive acid, succinct ketone oxime-chloroform extraction of palladium-NaOH reverse extraction-ammonia complexion palladium. The influence of liquid/solid ratio, temperature and time on the aqua regia leaching, extraction time, temperature, dosage of butyl ketone oxime dosage, chloroform for palladium extraction rate and reduction steps for the purification of the consumption of reagent were investigated. |
