Characterization of the new potentiometric sensor for thiabendazole determination

Thiabendazole (THIA) is a broad-spectrum anthelmintic and antifungal agent commonly used as a post-harvest fungicide in fruits and vegetables.[1] Due to the exposure to THIA through the diet, and its potential toxicity, it is necessary to develop simple, fast, selective and accurate methods for THIA determination. Potentiometric sensors could be suitable for that purpose.[2] The new potentiometric sensor for THIA determination with sensor material based on ionic pair of THIA and 5-sulfosalicylate, dibutyl sebacate (DS) as plasticizer and polyvinyl chloride was characterized. Response characteristics, dynamic response, influence of pH and interferences were determined using direct potentiometry.
