碘是合成人体甲状腺素,参与人体新陈代谢,影响青少年生长发育的重要微量元素之一,与人体健康密切相关。在许多缺碘地区,补碘已成为预防地方性甲状腺肿和克汀病,提高居民健康水平的主要对策。为此各种加碘口服液应运而生。为了加强对此类口服液的卫生监测,迫切需要建立一个简单、快速、准确地测定加碘营养口服液中碘的方法。为此,我们建立了用高氯酸混合液湿消化,碘量法测定加碘口服液中碘的方法,现报道如下。 Iodine is the synthesis of human thyroxine, involved in human metabolism, affecting one of the important trace elements of adolescent growth and development, and is closely related to human health. In many iodine deficiency areas, iodine supplementation has become a major countermeasure to prevent endemic goiter and cretinism and improve residents’ health. To this end all kinds of iodine oral solution came into being. In order to strengthen the hygienic monitoring of such oral liquid, there is an urgent need to establish a simple, rapid and accurate method for the determination of iodine in the iodized nutritional oral solution. To this end, we have established a perchloric acid mixture of wet digestion, iodometric method for iodine Determination of iodine oral solution, are reported below.
