Abstract

The determination of iodate in rain-water by neutron activation analysis is described. Iodate is separated by anion exchange. The determination limit of I is 0.02 μg·L⁻¹ for a 20 ml sample. The influence of the sea on the composition of rain-water is demonstrated by the analysis of coastal rain-water. The results indicate that inorganic iodine (I₂ and IO ₃⁻ ) is enriched in filtered coastal rain-water relative to the composition of sea-water.
