水中碘含量的分析,在医学上是调查和防治人与家畜的地方性甲状腺肿的重要依倨;在地质学上是寻找油田的重要参考指标。许多旧法测定需用水几公升至几十公升。从1937年Sandell 和 Kolthoff二氏倡用碘催化反应测碘后,出现了许多改良方法,可惜均不理想。1958年(1)1959年(2)国内报告了不同测定法,比文献记载的许多旧法有了改进;但是前一种方 The analysis of iodine content in water is an important medical basis for the investigation and prevention of endemic goitre of man and livestock. It is an important reference index in geology to find oil fields. Many old methods determine the need for water a few liters to tens of liters. From 1937, Sandell and Kolthoff II proposed iodine catalytic reaction after iodine, there are many improved methods, but unfortunately not all. 1958 (1) 1959 (2) Domestic reports of different assays have improved over many of the old methods documented in the literature; however, the former
