Abstract
New technology of bromine recovery from
bromine-containing brines is proposed. The technology is based on the anode
decomposition of metal chloride, oxidation of bromine with escaping chlorine,
extraction transfer of bromine from the anode electrolyte to the recycle
catholyte and reduction of bromine on a porous cathode. Commercial products of
the proposed method are individual salts of bromine. It was demonstrated that
the develop process is safe and involves low energy and reagent consumption.
