| Abstract: | The construction and performance characteristics of menispermine ion-selective electrode were described in this article. The electrode based on the ionpair complex of menispermine with TPB-Na was prepared with dibutye phtha-late as a plasticizer and PVC as a backbone.At the pH range 1.0-5.5, the Nerns-tion response range of the electrode is wide. The electrode can be used directly in rapid determination of menispermine in pharmaceutical preparation without any pretreatment. |
