Voltermetric And Amperometric Behaviour Of Polyaniline Modified Carbon Paste Electrode For The Analysis Of Atrazine

Abstract

The modification of the surface of the electrode with polyaniline greatly detected atrazine on the electrode. In this study, two types of sensors, i.e. bare and PANI modified carbon paste electrodes (CPE) were prepared and compared for their voltermetric and amperometric response towards atrazine. A low detection limit (LOD) of 0.3µmolL -1 and a dynamic working linear range of 1–18 µmolL -1 concentration of atrazine using PANI modified carbon paste electrode were obtained in comparison with No detection at on carbon paste electrode. No significant differences were encountered in the repeatability analysis of the electrodes. The proposed method (electrochemical) features unbiased identification of negative (blank) and positive samples. Importantly, this method provided a promising electrochemical sensing platform for atrazine analysis and its detection for human safety.
