Ion chromatography was applied to determine iodide remained in sulfuric acid aqueous solution after adsorption procedure. Iodide was determined in 0.25 M, 0.5 M and 1 M sulfuric acid solution on time variation. Because sulfuric acid in solution plays as an oxidizer, the concentration of iodide decreased with increasing concentration or sulfuric acid. Thereafter, sulfuric acid was neutralized with sodium hydroxide. Good linearity(r
