Abstract

This work evaluates the development of electrochemical processes for the oxidative degradation of persistent organic chemicals in waste waters, specifically the oxidation of cyanuric acid in the presence of NaCl at Cu/GO cathodes and Ti anodes. The experiment used a graphene oxide doped copper mesh cathode to examine different concentrations of cyanuric acid (30 mg/L, 40 mg/L, and 50 mg/L) and various concentrations of NaCl electrolyte (0.007mol/L, 0.03mol/L, 0.07mol/L, 0.1mol/L, and 0.2mol/L). In addition, the effect of pH (2, 4, 6, and 8), and applied current (0.200A, 0.150A and 0.100A) were studied. The Cu/GO electrode played a central role in the electrochemical cell for the wastewater treatment process. The results showed a concentration of 0.07mol/L NaCl electrolyte was the most effective electrolyte for all three cyanuric acid concentrations. At pH 6 and a current of 0.200A, the highest degradation efficiency was observed, with a removal rate of 38% of a 30 mg/L cyanuric acid in 60 minutes.

This study suggests that the rate of cyanuric acid degradation in wastewater using a GO/Cu cathode can be influenced by pH, electrolyte concentration, cyanuric acid concentration, and applied current.
