全自动盐碘分析仪测定食盐中碘含量的方法研究

Study on the Method of Measuring Iodine Content in Salt by Automatic Salt Iodine Analyzer

本文应用全自动盐碘分析仪,利用微量碘在水中呈现淡黄色这一特点,在波长为380 nm的条件下绘制标准曲线,测定食盐中的碘含量,从而建立了食盐中碘含量的无淀粉指示剂全自动盐碘分析仪测定方法。

In this paper,the automatic salt iodine analyzer was used to determine the iodine content in salt by drawing a standard curve at a wavelength of 380 nm by using the characteristic of tiny amount Iodine becoming light yellow in water.A method for the determination of iodine content in table salt by starch free indicator automatic salt iodine analyzer was established.
