本文根据碘酸钡与矿物气液包裹体中ＳＯ２－４交换反应析出的碘酸根与碘化镉反应析出碘，采用碘－四氯化碳萃取光度法间接测定ＳＯ２－４，取得了较为满意的结果。
In this paper, Iodate and iodide cadmium precipitated by the reaction of SO42- exchange reaction between barium iodide and mineral gas-liquid inclusions were analyzed to separate iodine. The iodine-carbon tetrachloride extraction spectrophotometry was used to determine SO2-4 indirectly, and the results were satisfactory result.
