Abstract A spectrophotometric method has been developed for the determination of oxidizing substances in food-grade hydrochloric acid. The method is based on the reaction of oxidizing substances with potassium iodide to form triiodide ion (I-3) whose absorbance is then measured at 485 nm. Oxidizing substances is reported as fig Cl2/mL. The method is applicable to oxidizing substances in the range of approximately 9-37 μgCl2/mL.
