Background: This research studied the effect of UV light on pentachlorophenol (PCP) removal in the electro-Fenton (EF) process.
Methods: PCP was used as the pollutant in this study. The effects of Fenton’s reagent, i.e. hydrogen peroxide concentration, solution pH, and treatment time by EF (EF) and photoelectro-Fenton (PEF) processes, were studied to determine rates of PCP removal. The results showed that a better performance and a high removal efficiency were achieved by coupling UV radiation and the EF process.
Results: EF processes required more time to remove PCP, while after a reaction time of 10 minutes, the PEF achieved a removal efficiency of 90.4%; this value is higher than the maximum efficiency of the EF process (83.44% after 40 minutes). The kinetic mechanisms of both processes were examined and
compared. The rate constants at optimum conditions were 0.0455 and 0.0579 min−1 for EF and PEF processes, respectively.
Conclusion: Removal efficiency was obtained in the order of PEF > EF.
Keywords: Ultraviolet rays, Reaction Time, Kinetics
