Zusammenfassung:	PURPOSE:To as possible prevent reduction in current efficiency of a membrane by specifying the quantity of Si and I in a supplied brine at a specified range. CONSTITUTION:In a method for obtaining >=30wt.% sodium hydroxide solution by sodium chloride electrolyzing using perfluoro cation exchange membrane, a product of concentration of Si and I expressed as ppm is to be
