Determination of Micro Amounts of Iodide in Dairy by Ion Chromatography with Pulsed Amperometric Detector
摘要
Abstract
A method is developed for the determination of micro amounts of iodide in dairy products by ion chromatography with pulsed amperometric detector.The dilute HNO3 solution was used as eluent and hydroxide column IonPac AS11 was selected .In the range of 0.005～0.1 mg/L, the concentration of iodide was linear with it's peak area, and the regression equation was Y=0.1112X-0.2490; r=0.9993.The RSDs of peak area and retention time were 0.971％ and 0.145％The detection limit of iodide was 0.02μg/L,The pulsed amperometric detector was used in the determination of micro amounts of iodide ( ＜ 100μg/L) in dairy samples, and a recovery of 89.08 ％ is achieved.关键词
