摘　　要：将含氯化碘的氯磺酸溶液在水中分解,以KMnO_4溶液滴定,使分解产物中的低价碘定量转化为IO_3^-,然后采用间接碘量法测定总碘量.相对误差为+0.97%,变动系数为2.1%.Determination of total content of iodine in the mixture of chlorosnlphonic acid and iodine chloride was made by using decomposition of the sample in cold water, oxidation of the resulting lower valent iodine compound into IO_(3)^(-) with KMnO4, and iodometry. The relative standard deviation was 2.1%, the relative error was + 0.97%.
