A new recovery Process of Pd in the lower-Pd alloy wastes is presented. Firstly, using hydrolytic property of Pd(NO3)2 (when heating), the Pd in the wastes is concentrated, and is PdO. H2O producted. Then, using a Pd[(NH3)2Cl2] method, Pd can be recovery and purified. The.direct recovery ratio of Pd reaches 92.8%, and recovery ratio is up to 98.4%. The new recovery method has the advantages of shorter processing cycle, less consumption of reagent and lower cost. It is one of effective methods of recoverying Pd from lower-Pd alloy wastes.
