在地方性甲状腺肿防治工作中,加碘食盐的现场监测日趋为山区半山区广大基层卫生工作者和盐业部门所重视。碘盐的现场监测不仅应了解食盐中是否有碘,重要的是要知道碘含量是否合格,以便及时指导碘盐加工,保证碘盐质量。我们曾用已报导的方法,试作定性和半定量测定,但因呈色消失过早,或呈色梯度与碘的含量比例关系欠佳而均感不理想。笔者经反复摸索,采用在酸性条件下使碘化钾碘盐中的碘化物转变为氢碘酸,氢碘酸被
In the endemic goiter prevention and treatment work, iodized salt field monitoring increasingly for the mountainous area of the vast grassroots health workers and salt sector attention. Iodized salt site monitoring should not only understand whether there is iodine salt, it is important to know whether the iodine content is qualified, in order to timely guide the processing of iodized salt to ensure the quality of iodized salt. We have tried both qualitative and semi-quantitative tests using the reported methods, but not all because of the early disappearance of the color or the poor relationship between the color gradient and the iodine content. The author after repeated exploration, the use of iodine salt in iodized salt under acidic conditions into hydroiodide, hydroiodide was
