FIELD: chemistry.
SUBSTANCE: method for extracting palladium from multicomponent solutions involves mixing the dithiooxamidated polysiloxane with a solution in which an acidic buffer medium is created at pH 2.0-4.0 for 30 minutes. In the process of sorption, selective separation of palladium from platinum and other metals accompanying in the solution takes place.
EFFECT: method makes it possible to increase the efficiency of palladium extraction by using a selective sorption material and creating optimal sorption conditions.
