一引言碘是防御和治疗由缺碘而引起的各项病症的药剂,而食盐中的碘又是人们从食料中得到这一元素的经常来源,所以对于食盐中含碘量的分析研究是很重要的。因此,轻工业部盐务总局委托高等教育部将「食盐中含微量碘的分析研究」作为科学研究专题,发给各校院研究,并指定西北大学,四川大学,福建师范学院和华东航空学院四校同时进行研究。 I. INTRODUCTION Iodine is an agent that protects against and treats various illnesses caused by iodine deficiency. The iodine in salt, on the other hand, is often the source for people to get this element from foodstuffs. Therefore, the analysis of iodine in salt is very important important. Therefore, the Salt Ministry of Light Industry entrusted the Ministry of Higher Education to “analyze and study the trace iodine in salt” as a scientific research topic and send it to all the universities for study and designated the four universities of Northwest University, Sichuan University, Fujian Normal University and East China Aviation University School at the same time to study.
