微量碘的测定,对地方病和医学研究有着重要意义。用离子选择电极法测定碘虽已得到一定程度的应用,但其精度不够理想。流动注射离子选择电极法,具有高采样率、低试剂和低试样消耗的优点,并可提高分析精度。在流动注射离子选择电极(下简称FIA-ISE)电位测定中,由于分散的样品区在电极 Determination of trace amounts of iodine, for endemic diseases and medical research is of great significance. Ion-selective electrode method for the determination of iodine has been a degree of application, but its accuracy is not ideal. Flow injection ion selective electrode method, with high sampling rate, low reagent and low sample consumption advantages, and can improve the analysis accuracy. In flow injection ion selective electrode (hereinafter referred to as FIA-ISE) potential measurement, due to the scattered sample area in the electrode
