食品添加剂碘酸钾的制备新法

Synthesis of Food Potassium Iodate by the Electrolysis

探讨了以 Cl-为媒介的间接电解法和碱介质金属阳极直接电氧化法合成含碘食品添加剂碘酸钾的实验条件 ,并进行了放大实验 ,总产率为 98.5% ,纯度为 99.2 % ,电流效率为 96.4%。产品各项质量指标均达到卫生部颁发的标准。整个制备过程工序少、无污物排出。

This paper studies the experimental condition of producing food grade potassium iodate by both indirect electrolysis in which Cl-acts a medium and directelectrolysis in alkaline solution at a special an- ode. Some scale up experiments are conducted and the total yield is 98.5% ,the purity of the product is 99.2 % ,the amperage efficiency is 96.4% . The quality indexes of the product meetthe standard in WS1- (XD0 8) - 92 Z. No pollutant is evacuated in the manufacture process.
