It was based on the quench effect of I - to the fluorescence intensity of the mercury fluorescein in basic medium. The degree of quenching is linable with the concentration of I - in the range of 0.～.0 μg/mL, the detection limit is 7 ng/mL.

据此 ,结合流动注射技术 ,建立了碘离子的流动注射荧光分析方法 ,碘离子在 0 . 0～ .0 μg/L质量浓度范围内具有良好的线性关系 ,检测下限为 7 μg/L .
