[Study on the determination of iodine by ICP-AES].
A method for the determination of iodine in iodo-calcium pieces by ICP-AES was studied. I- was turned to I2 by HClO4 and H2O2. The detection limit of iodine is 1 ng/mL. The sample was dissolved with water and was directly determined without seperating the precipitate in the bottom of volume flask. It was found that the precipitate attracted with I2 and the quantity of attracting would increase with delay time.
