https://doi.org/10.21122/1683-6065-2020-1-78-86

Abstract

The research methods for extraction of palladium from waste electrolyte solutions with the use of chloronitric extraction are described. The methods of investigation of the purification from harmful impurities by selective precipitation to obtain a refined palladium powder are given, the parameters on the technological processes are defined, use of the new technologies and equipment used are justified
