Abstract

An ion-selective electrode (ISE) was developed for the rapid determination of pseudoephedrine hydrochloride (PSEHCl) in pharmaceutical analysis. The electrode incorporates PVC-membrane with pseudoephedrine hydrochloride- phospohotungstate ion pair complex. The influences of membrane composition, temperature, pH of the test solution, and the interfering ions on the electrode performance were investigated. The sensor exhibits a Nernstian response for pseudoephedrine ions over a relatively wide concentration range (1.0×10-1 to 1.0×10-5 mol L-1) with a slope of 56.2 ± 0.5 mV per decade at 25 °C. It can be used in the pH range 4.0-10.5. The isothermal temperature coefficient of this electrode amounted to 0.0005 V/ °C. The membrane sensor was successfully applied to determination of pseudoephedrine hydrochloride in its tablets and syrup.
