A new method for determining iodine had been developed in ICP-AES. An oxidant, NaNO2 and a sample containing iodine ion were mixed in the PHD hydroid generation device, the producing iodine molecules were nebulized in nebulizer and then the iodine gas came into troch directly. The problem that the intensity of iodine decreases with the increase of time was solved. It was found that NaNO2 decreased the effect of Cl- in the low acidity. A detection limit of 14 ng.mL-1 was obtained and the RSD of the measurement for 2 micrograms.mL-1 of iodine was 1.2% (n = 10). The average recoveries of iodine were 99.44%. The method was applied to the determination of salt and seawater.
