本文用季铵盐研制了铋(Ⅲ)氯络阴离子选择电极,对季铵盐种类与敏感膜组成配比作了比较与选择,7402季铵盐[(CnH2n_(+1))_3CH_3NCl]作定域体的铋(Ⅲ)电极敏感膜,其较佳重量百分配比为活性物:增塑剂:PVC为25:45:30,而季铵盐THDA[(C_7H_(15))_3C_(12)H_(35)NI]作定域体的铋(Ⅲ)电极,活性膜较佳重量百分配比为25:67.5:30。两电板的线性响应范围、检测下限与斜率分别为5.0×10~(-5)—1.0×10~(-1)M、3.5×10~(-5)M、
In this paper, quaternary ammonium salt bismuth (Ⅲ) chloride anion selective electrode was prepared, the quaternary ammonium species and the sensitivity of the membrane composition ratio were compared and selection, 7402 quaternary ammonium [(CnH2n _ (+1)) _3CH_3NCl] The bismuth (III) electrode sensitive film in the domain has the best weight percent active ratio: the plasticizer: PVC is 25:45:30, while the quaternary ammonium salt THDA [(C_7H_ (15)) _ 3C_ (12) H 35 Ni] as the localized body of bismuth (Ⅲ) electrode, the active film preferably weight ratio of 25: 67.5: 30. The linear response range, detection limit and slope of the two plates are 5.0 × 10 -5 -1.0 × 10 -1 M, 3.5 × 10 -5 M,
