Abstract:	A new approach for increasing ferric reduction efficiency by the use of UVA lights and electric current as electron donors in a Fenton process has been developed to degrade organic toxic chemicals. The process can be applied to treat emerging pollutants such as pharmaceuticals and personal care products. Acetaminophen (ACT) was the target compound in this study. Effects of initial pH, Fe2+ loading, and H2O2 concentration were determined to test and validate a kinetic model for the oxidation of ACT by the photoelectro-Fenton process (PEF). Increasing the ferrous ion concentration from 0.01 to 0.1mM increased the hydroxyl radicals and then increased the degradation efficiency of ACT. The optimal H2O2 concentration for ACT degradation in this study was 25mM. The ACT removal efficiency for electro-Fenton and PEFs were 90% and 91%, respectively, as compared to 12% ACT removal efficiency using Fenton process.
