摘　　要：在国标规定的食盐全碘含量的常量测定、氧化还原滴定法的基础上改变条件,改成微量成分测定的分光光度法,用作工业盐中微量碘的测定,并对该方法进行了条件实验、精密度实验、回收率实验和工业盐碘含量测定的常规方法一溴水氧化光度法的比对实验等,提出了一个较为方便可靠的测量方法。We change the conditions on the basis of the determination of total iodine content in salt and the REDOX titration.The method is changed into spectrophotometry for the determination of trace iodine in industrial salt,and the condition experiment,precision experiment,recovery experiment and comparison experiment of bromide water oxidation spectrophotometry,which is the conventional method for the determination of iodine in industrial salt,are carried out.
