摘要：

We report here a derivatization headspace method for the analysis of inorganic iodine in water. Samples from Lake Mead, the Las Vegas Wash, and from Las Vegas tap water were examined. Lake Mead and the Las Vegas Wash contained a mixture of both iodide and iodate. The average concentration of total inorganic iodine (TII) for Lake Mead was similar to 90 nM with an iodide-to-iodate ratio of similar to 1. The TII concentration (similar to 160 nM) and the ratio of iodide to iodate were higher for the Las Vegas Wash (similar to 2). The TII concentration for tap water was close to that of Lake Mead (similar to 90 nM); however, tap water contained no detectable iodide as a result of ozonation and chlorine treatment which converts all of the iodide to iodate.
