Abstract

Способ получения хлора высокой чистоты электролизом солевого раствора хлорида натрия, загрязненного бромидами в мембранном электролизере, согласно которому солевой раствор окисляется, чтобы превратить бромиды в нем в броматы.A method for producing high-purity chlorine by electrolysis of sodium chloride saline solution contaminated with bromides in a membrane electrolyzer, according to which the saline solution is oxidized to convert bromides in it into bromates.
