Abstract

An online analytical system using ion chromatography (IC) followed by inductively coupled plasma mass spectrometry (ICP-MS) was developed for the separate determination of I and IO 3 in aqueous solutions with a detection limit 0.1–1 μg 1/1. The total iodine concentration was also directly determined by ICP-MS. Iodine in several environmental samples (i.e., rain, river water, brine, and soil solution) was successfully determined with information on its chemical form. The release of I into soil solution with decreasing Eh was observed in an incubation experiment with flooded soil. An iodine form other than I and IO 3 was observed in several environmental samples.
