抓好碘盐质量是防治碘缺乏病的关键。我省规定抽检的出厂盐应有90％碘含量＞40mg／kg[1]。本文针对碘盐加工过程中易受干扰的几种因素做了实验观察分析。1材料与方法1．1碘酸钾：采用“方棱牌”，经粉碎过60目筛。1．2母盐：惠安盐场产的细盐，投碘量（≥40mg／kg）与盐产量按 Grasp the quality of iodized salt is the key to prevention and treatment of iodine deficiency disorders. The provisions of our province sampling of the factory salt should be 90% iodine content> 40mg / kg [1]. In this paper, iodized salt for the processing of several factors susceptible to interference in the experimental observation and analysis. 1 Materials and Methods 1.1 Potassium iodate: The “square edge card”, after smashing 60 mesh sieve. 1.2 Parent salt: salt produced in Huian salt, iodine dose (≥ 40mg / kg) and salt production by
