Method for preparation of palladium adsorbing resin and for separation of palladium by using the palladium adsorbing resin

摘要

The invention new palladium adsorption infiltrating resin, a method of manufacturing the same, and as using it relates to a method of recovery of palladium, specifically to heterocyclic containing imidazole represented by the benzimidazole or to formula (2) represented by the general formula (1) method was a cyclic amine is infiltrating the form of a palladium adsorption infiltrating resin, heterocyclic amines infiltration into the polymer resin, the polymer pores within the polymer resin, the polymer pores by alkylating the nitrogen atom of the heterocyclic amine to prepare a palladium adsorption infiltrating resin, and method for selective recovery of the eluted palladium with an acid solution to saturate the palladium adsorption infiltration resin with an acid solution of adsorbed palladium after changing the salt form of infiltration resin with a halogen anion by infiltration resin of acid type and palladium is adsorbed palladium It comprises a complexing agent for adsorption resin infiltration Is a directed to a method for recovering palladium by desorption palladium put in the acid solution, the palladium adsorption infiltration composition according to the present invention has improved adsorptivity and selectivity for palladium because adsorption and desorption of palladium rapidly eluting with an acid solution It can be recovered in high yield and the palladium, and also has a lower manufacturing cost advantages as well as a high degree was the reaction stage less than in the conventional method yields.; In Formula 1 and Formula 2, X Is a halogen atom, NO ₃^- represents an anion, including R represents an alkyl group of C ₁ ~C _10.
