Title: [Determination of trace iodine based on kinetic-spectrophotometry with malachite green-chloramine T system].
Abstract: In this paper, a new kinetic-spectrophotometric method for the determination of trace amount of iodine has been proposed. It is based on the iodine catalysed the reaction of malachite green oxidized by chloramine T in hydrochloric acid medium. The method is sensitive, simple and with good selectivity. The linear range of determination of iodine is 0-48 micrograms.L-1, the detection limit is 4.9 x 10(-10) g.mL-1. The method has been used for the determination of trace amount of iodine in food with satisfactory results.
