摘要
报道一种以盐酸培氟沙星与溴汞酸盐生成的分子缔合物为电活性物质的新型涂碳PVC膜培氟沙星选择电极。在pH 1 .5～ 4.5范围内 ,电极对培氟沙星的Nernst响应范围为 1 .0× 1 0 - 2 ～ 5 .0× 1 0 - 5mol/L ,检测限为 4.2× 1 0 - 6mol/L。方法的平均回收率为 98.5 % ,RSD为 1 .0 %
A coated carbon PVC membrane pefloxacin selective electrode based on complexation of pefloxacin and potassium mercuric bromide was described. The electrode was used for determination of pefloxacin in tablets. The electrode showed Nernst response for pefloxacin with a slope of 31.0 mV over the concentration range of 1.0×10 -2 ～5.0×10 -5 mol/L and detection limit of 4.2×10 -6 mol/L. The average recovery is 98.5% and RSD 1.0%( n =5).
