Determination of miro iodine in table salt by coupling reaction flow injection chemiluminescence analysis

偶合反应流动注射化学发光法测定食盐中微量碘杨维平（陕西师范大学民族科教研究中心，西安７１００６２；作者，男，３３岁，副教授）目前，全世界有１０亿人缺碘，中国就有４亿多人生活在缺碘病区．我国主要是依靠食盐中加碘的方法达到补碘的目的．因此，建立一个灵敏度...

A chemiluminescence method for the determination of micro iodine based on Luminol Fe 3+ I - system is developed. The linear range for iodine is 1.0×10 -8 ～1.0×10 -5 g/mL with a detection limit of 6.0×10 -9 g/mL and the relative standard deviation (RSD)≤3.5%. The method gives good results to iodine determination in table salt.
