前言近年来,各种离子选择电极的研制及应用日益发展,对碘离子选择电极的研究也有不少报导。我们采用AgI/Ag_2S克分子比1∶1的难溶盐沉淀混合物及纯AgI沉淀压制的碘离子选择电极,性能良好,能满足一般分析要求。应用碘离子选择性电极测定汞,资料报导在1—2N的硝酸或硫酸溶液中,以碘离子选择电极测定汞,在[Hg~(2+)]=10~(-7)—10~(-8)M范围内 Preface In recent years, a variety of ion-selective electrode development and application of the growing development of iodine ion selective electrode research there are many reports. We use AgI / Ag_2S molar ratio of 1: 1 salt precipitation mixture of precipitation and pure AgI precipitation of iodine ion selective electrode, good performance, to meet the general analysis requirements. Determination of mercury using iodide ion selective electrode, the data reported in the 1-2N nitric acid or sulfuric acid solution, the iodide ion selective electrode mercury, [Hg ~ (2)] = 10 ~ (-7) -10 ~ ( -8) M range
