Ultrasound-Assisted Synthesis of Hybrid Phosphomolybdate-Polybenzidine Containing Silver Nanoparticles for Electrocatalytic Detection of Chlorate, Bromate and Iodate Ions in Aqueous Solutions

Abstract

Herein, we report a hybrid electroactive material composed of silver nanoparticle-embedded polybenzidine matrix containing phosphomolybdic acid as the active inorganic component by an ultrasound-assisted method for the electrochemical detection of chlorate, bromate and iodate ions in aqueous solutions. The prepared hybrid material was characterised for its physicochemical properties: X-ray diffraction and transmission electron microscopy analyses provided evidence for the presence of silver nanoparticles (~12 nm) in the hybrid material. The synthesized hybrid material was successfully fabricated on a glassy carbon electrode, and cyclic voltammetry was used to probe its electrochemical proper..
