Abstract

The degradation of bisphenol A (BPA) by nickel sulfide supported on graphene oxide (NiS/GO) and cobalt sulfide supported on graphene oxide (CoS/GO) composite materials was investigated. The catalysts were studied to determine the optimal conditions for BPA degradation using electrocatalysis. Electrocatalytic trials were performed using varying parameters, which included electrolyte concentrations of 1.0 g/L, 2.0 g/L, and 4.0 g/L Na2SO4, pHs of 2, 4, and 6, and constant currents of either 0.100 A or 0.200 A. During the reaction samples were taken before the current was applied and 30 minutes and 60 minute intervals to observe the degradation of BPA with respect to time. The synthesized catalyst samples were analyzed using both XRD and SEM the SEM was used to analyze the electrode after the reaction. The degradation of the BPA was followed using HPLC, and the reaction products were identified using LC-MS/MS/MS. All the degradation reactions showed first-order kinetics for the degradation of BPA.
