Abstract
Three Potentiometric sensors were developed for the determination of Salicylates using Carbon Paste Electrodes (CPEs) and Modified Carbon Paste Electrodes(MCPEs) based on a salophen metal complex and two thiourea derivatives.The different sensors were , fully characterized and optimized in terms of composition, pH effect, selectivity, response and lifetimes The prepared sensor showed high selectivity against similar anions (i.e. ClO⁻ ₄ , benzoate, I⁻ SCN⁻).Selectivity was confirmed by calculating formation constant(KÝ) using sandwich membrane method,The sensors were applied successfully used for the determination of salicylate anion in different pharmaceutical formulations, Aspocid® and Aspirin®
