定性分析的任务是鉴定试样中所含的元素或离子,致于确定这些组分含量的多少,则是定量分析的任务。用于碘盐定性的方法有多种,但无论那种试剂或制成什么剂型,其基本原理都是一样的,即经过氧化还原反应把化合态的碘变成碘的单质,而后显色,从而确定碘的存在与否。八○年九至十二月间,我们对已知几种
Qualitative analysis of the task is to identify the elements contained in the sample or ion, to determine the amount of these components, is the task of quantitative analysis. There are many ways for the qualitative determination of iodine salt, but no matter what kind of reagent or made into the dosage form, the basic principle is the same, that is, after the oxidation-reduction reaction of iodine into a chemical compound of iodine, and then color, To determine the existence of iodine or not. From September to December 1980, we knew about several
