Аннотация
An ion-selective potentiometric sensor with an ionophore is developed based on the ion associate of artificial food colorant E133 and a cetylpyridinium cation. The main electroanalytical parameters of the sensor are evaluated: linearity range of the response, pH effect, and the effect of temperature on the electrode performance and selectivity. The sensor is used to determine E133 in the Powerade beverage. The accuracy of the determination is confirmed by an extraction–photometric method.
