| Abstract: | A new coated wire polyvinyl chloride membrane-tramadol selective electrode based on tramadol and bismuthiodile molecular association complex is reported.The electrode showed Nernst response for tramadol ranges between 2.2×10~(-3) to 2.0×10~(-5)mol/L with a slope of 56mV/pC.The detection limit is 1.6×10~(-5)mol/L.The electrode has fast resporse and good reproducibility.The electrode has been used for the determination of tramadol in medicinal tablet by the standard curve method.The procedures of this method are simple and the results obtained agree with this of pharmacopeial method. |
| Keywords: | tramadol ion-selective electrode coated wire |
