仲裁法与国标法对川盐中碘含量的测定结果分析

Analysis on Detection of Iodine Content in Salt Produced in Sichuan by Arbitration Method and National Standard Method

目的为了准确的测定川盐中碘的含量,比较仲裁法和国标法测定川盐碘含量和测定碘酸钾标准物质中碘含量结果的差异。方法分别用仲裁法和国标法对抽取的288个样品及标准物质进行测定。结果288个样品的碘含量国标法和仲裁法测定结果的差异有统计学意义,碘酸钾标准物质结果差异无统计学意义。结论在食盐碘的测定中,对川盐的测定应用仲裁法能准确反映碘含量。

Objective To detect the iodine content in salt produced in Sichuan, and compare the difference on the iodine content detection by arbitration method and national standard method.
