NON-ENZYMATIC SENSING OF D-SORBITOL USING POLYANILINE-COATED STAINLESS STEEL ELECTRODES- Abstract

The Potentiodynamic deposition of polyaniline on stainless steel electrodes has been carried out using the anionic surfactant sodium tetradecyl sulphate in the presence of acetic acid. The PANI-coated SS electrode was characterized using different spectroscopic and microscopic techniques. The efficacy of the electrode was analyzed for non-enzymatic sensing of D-sorbitol. Amperometric and impedimetric studies reveal the suitability of the electrode for sensing. A detection limit of 5 μM along with a linear range spanning of 75–637 μM and sensitivity of 0.027 μA μM−1 is deduced from the amperometric analysis.
