摘要
研究了利用碘酸钙废液回收氯化钾、碘酸钙和碘的工艺技术。其主要成分氯化钾,经浓缩、除杂质离子、还原、树脂交换回收碘、精制等工艺过程得到了高度提纯。应用本工艺既消除了废水污染,也提高了产品的综合经济效益。
Separation and recoverg of potassium chloride, calcium iodate and iodine from the waste liguid of calcium iodate is studied. As one of the essential component of the liguid potassium chloride is purified highly in the course of concentrating , removing foreign ion, reducing, recovery iodate with ion exchange resin and refining. So that,the enviro-mental pollution can be eliminated, and the comprehensive economic benefit is also improved.
