Description
Summary:This work describes the catalytic property of silver nanoparticles decorated graphite electrode (Ag−CPE) for the thiamethoxam reduction. The prepared powders were characterized by X-ray diffraction (XRD), and the crystallite size of silver nanoparticles was calculated by the Scherrer equation. On the other hand, the electrochemical techniques were employed to study the nanoparticles size effect on the electrocatalytic reduction of thiamethoxam (TMX). The reduction current was proportional to thiamethoxam concentration in the range of 1.0 × 10−4 to 1.0 × 10−3 mol l−1 with a detection limit of 3.6 × 10−5 mol l−1. The modified electrode exhibited excellent reproducibility, accuracy and long-term stability of usage in water samples.
