AbstractPhenol, as an extensively used compound, could be detected in a great variety of environmental water. In this study, the environmental behavior of phenol photo-induced degradation in aqueous solution in the presence of nitrate (NO3-) and nitrite (NO2-) under simulated sunlight irradiation was investigated. The results showed that the degradation of phenol followed pseudo-first order kinetics model in both NO3- and NO2- conditions and the phenol disappearance rate decreased with decreasing nitrite concentration. The effect of environmental parameters including pH and humic acid on the phenol degradation by NO3- and NO2- were also performed. The photodegradation rates of phenol were strongly influenced by these parameters. In addition, the hydroxyl radical (center dot OH) formation was identified by the photoluminescence spectra (PL) using terephthalic acid as trapping molecule and the pathways of center dot OH generated in the phenol degradation by the NO3- and NO2- ions are proposed.
