The kinetics study of the photodegradation of chlorophenols in aquatic environment

The rates of photolysis degradation of 3-chlorophenol, 2,4-dichlorophenol, pentachlorophenol in an aqueous solution were determined. The results obtained show that under the experiments conditions, the rate constants decreased in the PCP > 2,4-DCP> 3-CP order. The quantum yields of the photolysis for the selected chlorophenols at 254 nm were also studied. The kinetic curves, the reaction rate and the rate constant reaction of the photodegradation of chlorophenols were presented. The main photodegradation pathways and primary products were identified.
