PROCESS FOR THE PURIFICATION OF AN AQUEOUS SOLUTION OF AN ALCALINE METAL CHLORIDE BY THE REMOVAL OF AMMONIUM ND IODIDE

摘要

the present invention is a method ofpurification of an aqueous solution of metal chloridealkali containing iodine, chiefly in the formin which iodine iodide oxide up to degreeoxidation, i.e., in the form of periodate andit eliminates the periodate. it is also at the same timethe destruction of the ammonium oxidation in nitrogenfollow up of a molecular gas).
