| Abstract: | A method for the determination of iodine in ido calcium pieces by ICP AES was studied.I - was turned to I 2 by HClO 4 and H 2O 2.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 I 2 and the quantity of attracting would increase with delay time. |
