| Abstract: | A new coated wire polyvinyl chloride membrane- procaine selective electrode based on procaine and iodine molecular association complex is reported. The electrode showed Nernst response for pro- caine ranges between 1.0×10^-1 to 7.9×10^-5mol/L with a slope of 51mV/pC. The detection limit is 5. 0×10^-5 mol/L. The electrode has fast response and good reproducibility. The electrode has been used for the determination of procaine in procaine injection by the standard curve method. The procedures of this method are simple and the results obtained agree with this of pharmacopeial method. |
