季铵、碱性染料阳离子是研制阴离子选择电极的常用离子交换定域体。这类定域体对ISE性能的影响文献中已有讨论。但均未指出可用于筛选离子交换定域体的适宜的物理量,而研制液膜电极时,怎样选择有机溶剂,目前也无规则可循。本文以五种烷基吡啶、三种季铵(氯代烷基三甲铵)四种碱性染料为定域体,研制了液膜、PVC膜
Quaternary ammonium, basic dye cation is the development of anion selective electrode common ion exchange domain. The effect of such localized domains on ISE performance has been discussed in the literature. However, none of the suitable physical quantities that can be used to screen the ion-exchange delocalized body has been pointed out. However, at present, there is no rule for how to choose an organic solvent when developing a liquid-membrane electrode. In this paper, five alkylpyridines, three quaternary ammonium (chloroalkyl trimethyl ammonium chloride) four basic dyes as localized body, developed a liquid film, PVC film
