We determined iodine levels in samples from the process of salt making by the ICP-AES method with a flow injection device and fluorine levels by absorptiometry using alfusone, and the following results were obtained. 1) On the analysis of fluorine in high-salinity samples, the recovery ratio with pretreatment by the distillation method was greater than 93%. 2) Fluorine was not concentrated by the ion-exchange membrane method, but iodine. The permaselectivity of iodine against chloride ion with an ion-exchange membrane was approximately one. 3) A large percentage of IO<SUB>3</SUB><SUP>-</SUP> in seawater was deoxidized to I<SUP>-</SUP> by the ion-exchange membrane method. 4) The iodine content of the samples in the process of concentration were almost the same as their fluorine content.
