Rhodium recuperation and purification after separation from other metals comprises dissolution in molten salt and hydrogen peroxide treatment, for rhodium films deposition

NOVELTY – The rhodium recuperation and purification after separation from other metals has dissolution in molten salt for precipitation of contaminating metals and purification of the electrolytic rhodium solutions. Treatment with hydrogen peroxide is followed by use of the solution in electrochemical baths, e.g. for deposition of films of rhodium. USE – In industrial chemistry.

Main Application Field

M25 (Production and refining of metals other than iron – including ore treatment, extraction, working up scrap, obtaining specific metals, control testing methods (C22B).)
