Decomposition of a Waste Catalyst Containing Palladium in the Surface Layer
摘要
The results of experimental studies on the decomposition of a waste catalyst containing a precious metal (palladium) in the surface layer by the acidic method are presented. Two approaches implying complete dissolution of the catalyst, including its support, and selective palladium extraction (with minimum dissolution of the catalyst support) are considered. The optimal decomposition conditions providing extraction of at least 90% of the palladium into the solution are selected.
