摘　　要：报道了一种以曲马多碘化物与碘化铋的分子缔合物为电活性物的新型全固态选择电极,电极的能斯特响应范围为6.3×10^(-2)～3.2×10^(-5)mol·L^(-1),斜率为50mV/pC,检测限为0.6×10^(-5)mol·L^(-1)。此电极响应迅速,重现性好。用此电极以标准曲线法对注射液中的曲马多进行了测定,结果与紫外分光光度法相符。The construction and performance characteristics of a coated carbon PVC membrane all-solid-stale tramadol ion-selective eleclrode were reported.The electrode showed Nernst response ior Iramadol with a slope oi 50mV/pC over the concentration in range of 6.3×10-2~3.2×10-5 mol·L-1.The detection limit is 1.6×0-5 mol·L-1.The resull of determination of tramadol in Iramadol injection is in agreement with that of ultraviolet spectrophotometry.
