Abstract

PURPOSE:To provide a highly purified aq. soln. of an alkali metal salt for electrolysis using an ion exchange membrane by purifying the unpurified aq. soln. in the presence of a specified foaming agent and/or a chelate bond forming reagent by flotation so as to remove alkaline earth metals and suspended solid.
