食盐中含碘量较少,一般均在万分位以下。关于碘量的测定,文献中曾提到一些不同的方法,[1],[2],[3],[4],[5],[6],[7],[8],[9],[10],[11],[12],[13]。本文仅拟作出适合于目前可以在国内推广的快速方法。对象暂限于四川盐产。测定灵敏度暂以0.0001%(按固体盐样计)为目标。 Iodized less salt, generally below the millionth place. There are several different methods mentioned in the literature for the determination of iodine content [1, 2, 3, 4, 5, 6, 7, 8, 9 ], [10], [11], [12], [13]. This article is intended to be made only for the current method of rapid promotion in the country. Target temporarily limited to salt production in Sichuan. The assay sensitivity is targeted at 0.0001% (based on solid salt sample).
