| Abstract: | In this paper, a new coated carbon polyvinyl chloride membrane diphenhydramine selective electrode based on diphenhydramine and iodine molecular association complex is reported. The electrode showed Nernst response for diphenhydramine ranges between 3.2×10 -2～2.6×10 -5mol/L with a slope of 29 mV/pC. The detection limit is 1.6×10 -5mol/L. The electrode has fast response and good reproducibility. The electrode has been used for the determination of diphenhydramine in medicinal tablets by the standard curve method. The procedure of this method is simple and the reseuts obtained agree with those of pharmacopeial method. |
