| Abstract: | In this paper,a new coated wire polyvinyl chloride membrane-dipyridamole selective electrode based on dipyridamole and iodine molecular association complex is reported.The electrode showed Nernst response for dipyridamole ranges between 1.0×10-2~4.0×10-5mol/L with a slope of 56 mV/pC.The detection limit is 2.6×10-5mol/L.The electrode has fast respons and good reproducibility.The electrode has been used for the determination of dipyridamole in medicinal tablet by the standard curve method.The procedures of this method are simple and the reseuts obtained agree with those of pharmacopeial method. |
