FAST AND EASY SYNTHESIS OF CoAu/rGO NANOCOMPOSITES FOR THE DETECTION OF As³⁺ IONS IN AQUEOUS SOLUTIONS
The CoAu/rGO nanocomposite was synthesized using a simple and scalable method by depositing cobalt (Co) and gold (Au) nanoparticles onto reduced graphene oxide (rGO), and investigated as a material for the detection of As³⁺ ions in water. Under optimized acidic conditions, the electrode exhibited a well-defined peak of As⁰ oxidation to As³⁺ and high sensitivity. Detection was successfully achieved over a wide concentration range (30–1000μM), with two linear regions and an appropriate detection limit. The electrode demonstrated good electrochemical response in real samples, confirming its applicability in water analysis .
