羟苄唑是治疗急性出血性结膜炎的药物,其PVC膜电极的研制及应用尚未见报导。作者据以前工作,以羟苄唑—四苯硼离子缔合物为活性物质研制成羟苄唑PVC膜电极(Ⅰ)及PVC膜石墨棒电极(Ⅱ)。经测试,(Ⅰ)的能斯特响应范围为1.0×10~(-2)—4.0×10~(-5)M,检测下限为5.6×10~(-6)M;对羟苄唑的回收率为100.2—105.1％(Ⅱ)的能斯特响应范围为1.0×10~(-2)M—4.3×10~(-5)M,检测下限为8.9×10~(-5)M,回收率为98.6—
Benzoxybenzole is a drug for the treatment of acute hemorrhagic conjunctivitis. The development and application of its PVC membrane electrode has not been reported yet. Based on the previous work, the authors developed the hydroxybenzazole PVC membrane electrode (Ⅰ) and the PVC membrane graphite rod electrode (Ⅱ) by using the combination of benzyl alcohol and tetraphenylborate ion complex as the active substance. After testing, the Nernst response range of (Ⅰ) was 1.0 × 10 -2 -4.0 × 10 -5 M with the detection limit of 5.6 × 10 -6 M. The Nernst response range of 100.2-105.1% (Ⅱ) was 1.0 × 10 -2 M-4.3 × 10 -5 M, the detection limit was 8.9 × 10 -5 M, The recovery rate was 98.6-
