Here, we report a novel method for assembling reduced graphene oxide (RGO) and Ag nanoparticles on a carbon paste electrode successively to form a stable multiple junction for cyanide determination in alkaline medium. scanning electron microscopy techniques are used to investigate the the surface morphologies. The AgNPs/CPE was used for the determination of cyanide (CN−) in solution (pH 12). The cyclic voltammetry (CV) and square wave voltammetry (DPV) methods were used for the determination of CN−. The linear dynamic range from 0.1 μM to 23.0 μM and a detection limit was found to be 0.02 μM (S/N = 3) by DPV method. Interference studies were performed with typical anions present in natural and waste water [1-4].
