| Abstract: | A new catalysate depigmentation photometric kinetic method for the determination of trace Iodine was established based on the catalytic action of Iodine on the oxidative fading reaction between Catalytic-oxidation and KIO3 on the condition of microwave digestion. The ending RSD%1.32%-4.40%, CV%97.60%-101.70%.Been used for the determination of Iodine in biomaterial foodstuff sample and etc. with a satisfactory result, the method is quick, accurate, simple and convenient. |
