报道一种以曲马多与四苯硼的缔合物为电活性物的新型PVC膜曲马多选择电极，电极的Nernst响应范围为1．0×10~(－2)~2．1×10~(－5)mol/L；斜率为57mV/pC；检测限为7．2×10~(-6)mol/L。此电极响应迅速，重视性好，用此电极以标准曲线法对药物中的曲马多进行了测定，此法简便，结果与紫外分光光度法相符。
A new type of PVC membrane tramadol selective electrode with the association of tramadol and tetraphenyl boron was reported. The Nernst response range of the electrode was 1.0 × 10 -2 ~ 2.1 × 10 -5 mol / L; the slope was 57mV / pC; the detection limit was 7.2 × 10 -6 mol / L. The rapid response of the electrode, the importance of good, with the electrode using standard curve method for the determination of tramadol in the drug, this method is simple, the result is consistent with the UV spectrophotometry.
