METHOD FOR SEPARATING METAL HYDROGENATED COMPLEX COMPOUND AND ITS OXIDANT AND MEMBRANE SEPARATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a safe and simple method for separating a metal hydrogenated complex compound and its oxidant which coexist in an alkaline solution without imposing environmental load and to provide a membrane separation apparatus. SOLUTION: A minutely porous membrane having the specified sodium chloride-impermeable rate is used when separating the metal hydrogenated complex compound and its oxidant which coexist in the alkaline solution.
