摘　　要：本文报道了胃复安选择性电极的研制及应用.研究了活性物膜含量、增塑剂、电极结构等因素对电极性能的影响.以四苯硼作为离子交换体时,电极的线性范围为2.0×10^(-2)～8.0×10^(-6)mol/L,斜率57.4mV/pC,检测下限4.2×10^(-6)mol/L.用于胃复安的分析结果良好,回收率在97～104%之间,片剂胃复安的含量测定与药典法一致.The preparation and application of selective electrode of metoclopmidum were reported. Using the metoclopramidum-tetr.aphenyl borate associated: complex as the electroactive material, the linear range of electrode is 2.0 × 10-2~ 8.0 × 10-6mol/L, the slope is 57.4 mV/decade, the detective limit is 4.2×10-6 mol/L, the recovery is from 97-104%. By potentiometry, the result of the analysis of metoclopramidum in tablet corresponds well to the result by the method in the Pharmacopeia of People's Republic of China.
