Abstract: PURPOSE: Provided is a method for recovering iodine from nitrogen compound solution using ion exchange resin. CONSTITUTION: The method comprises the steps of (a) passing nitrogen compound solution through a column filled with weak basic anion exchange resin, (b) recovering the anion exchange resin by passing 0.1-2N basic aqueous solution through the column at a temperature of 40-90°C, and (c) oxidizing the solution passing out the column at the step (b) by feeding persulfate-based oxidizing agent, wherein the nitrogen compound is selected from a group consisted of N-methyl-2-pyrrolidinone, N,N-dimethylformamide, pyridine, pyrrolidine and pyrrolidinone.
