| titleOfInvention | Method for recovering iodine from organic iodine compound-containing waste liquor |
| abstract | PURPOSE: To readily recover iodine from an organic iodine compound-containing waste liquor in high yield, by reducing the organic iodine compound-containing waste liquor, deiodinating the reduced waste liquor, oxidizing the deiodinated waste liquor, driving off liberated iodine with air and absorbing the iodine in an absorbing solution. n CONSTITUTION: A waste liquor, generated in a process for producing roentgenographic contrast media, industrial germicides, etc., and containing an organic iodine compound (e.g., 5-amino-2-iodoisophthalic acid) is recovered. The organic iodine compound in the above-mentioned waste liquor is then re duced by catalytic hydrogenolysis reaction, reductive reaction with metallic zinc, etc., or electrolytic reductive reaction and deiodinated. The treated liquor is subsequently oxidized with an oxidizing agent (e.g., sodium hypochlorite) to liberate iodine, which is then recovered by introducing air, driving off the liberated iodine from the treated liquor and absorbing the iodine in an alkaline aqueous solution or reductive aqueous solution (e.g., aqueous solution of sulfu rous acid). n COPYRIGHT: (C)1989,JPO&Japio |
