摘要：
The pH effect on the quinidine ion-selective electrode performance and its electroactive material composition were investigated. It was found that variation of the pH in the bulk solution can alter the ion-pair composition in the membrane phase, thus affecting the electrode behaviour. A capacitor model was suggested for the description of the electrode response.
