Abstract:

IN THIS CONCEPT, ORGANIC IMPURITIES ARE REMOVED BY ELECTROLYSIS; INORGANIC IMPURITIES BY ELECTRODIALYSIS. IN PREVIOUS WORK A PROBLEM WAS CAUSED BY THE RELATIVE INSOLUBILITY OF POTASSIUM PERCHLORATE, WHICH PRECIPITATED WITHIN THE ELECTRODIALYSIS MEMBRANES CAUSING THEM TO CEASE FUNCTIONING. EFFORTS WERE UNSUCCESSFUL IN PREVENTING THE FORMATION OF PERCHLORATES IN THE ELECTROLYSIS STEP, WHICH WOULD HAVE OVERCOME THE PROBLEM. A UNIQUE SOLUTION IS PROPOSED HERE. A REGENERABLE CATION EXCHANGE RESIN BED REMOVES THE TROUBLESOME POTASSIUM IONS AND REPLACES THEM WITH SODIUM IONS, WHICH FORM A MORE SOLUBLE PERCHLORATE SALT. REGENERATION IS ACHIEVED WITH THE CONCENTRATED SODIUM-RICH BRINE FROM THE ELECTRODIALYSIS STEP. NO EXPENDABLE MATERIALS ARE REQUIRED.
