Abstract

The photodegradation of phenol and hydroquinone in the presence of hydrogen peroxide (H2O2), sodium hypochlorite (NaOCl), and ammonium persulfate ((NH4)2S2O8) has been studied. The highest phenol and hydroquinone degradation efficiency of 99.9% was achieved in the UV/H2O2 and UV/S2 \({\text{O}}_{8}^{{2 - }}\) systems. It was found that in the presence of hydrogen peroxide and ammonium persulfate, the rate of phenol degradation increased by 11.3 and 3.8 times, respectively, while that of hydroquinone increased by 11.9 and 9.6 times, respectively. The results of the study suggest that ultraviolet-based advanced oxidation processes (UV AOPs) may be promising methods for treating phenol-containing wastewater.
