Abstract: A method for the determination of iodine in iodized salt by gas chromatography was reported in this paper.The linear range of the method was 0~100μg/L,the detection limit was 3μg/L,the recoveries were between 97.7%~102.7% and the RSDs were 4.25%(25μg/L)and 2.19%(70μg/L).The method was simple,rapid and reliable.
