Abstract

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.
