应用碱性染料研制离子选择电极,通常先用沉淀法将碱性染料与待测离子制成缔合物沉淀,再经洗涤,干燥后作为电活性物质,如文献[1]的亮绿—HgI~-_3离子缔合物、文献[2][3]的乙基紫—HgBr~-_3离子缔合物,也可用萃取法制备离子缔合物,如文献[4]的乙基紫GaCl_4~-缔合物。本文直接用碱性染料维多利亚蓝为电活性物制制备PVC膜Hg(Ⅱ) Basic ion-selective development of ion-selective electrode, usually by precipitation method will be the basic dye and the analyte ions made of association precipitation, and then washed and dried as an electroactive material, such as the literature [1] bright green-HgI ~ -_3 ion association, et al [2] [3] ethyl violet-HgBr ~ -3 ion association can also be prepared by the extraction of ion-association compounds such as the literature [4] ethyl violet GaCl_4 ~ Associations. In this paper, PVC film Hg (Ⅱ) was prepared directly from basic dye Victoria Blue as an electroactive material.
