【摘要】 介绍用于碘含量定值的碘盐标准物质的研制方法。选取一定量的精制碘盐，经标准物质制备，均匀性检查，稳定性检查，合格后，选择3个试验室，用碘盐监测的国家标准（GB／T13025．7－91）[1]对标准物质进行碘含量的定值，含碘量为：26．63±0．36mg／kg，标准物质编号为：冀卫—606。更多还原

【Abstract】 This paper introduced the method of studing reference material of iodine-salt. Certain amount of refined iodine-salt was selected and made into the reference material. After homogeneity and stability testing. It was up to standard. The concentration of iodine was detected by GB/T 13025. 7-91 in three selected laboratory. The resull was 26. 63 ±0. 36mg/kg.
