Abstract. A kinetic model of degradation of 2-chlorophenol waste water by the photolytic hydrogen peroxide oxidation method was proposed. A high-pressure mercury lamp located in the center of the photoreactor was used as the UV radiation source and hydrogen peroxide was added as a catalyst which proved to be effective for the degradation of 2-chlorophenol. To calculate the reaction rate constants, two different types of batch experiments were conducted, UV radiation alone and hydrogen peroxide with UV radiation. A fourth-order Runge-Kutta method with the Rosen-Brock optimization algorithm were used to calculate the reaction rate constants from the experimental data. It was shown that the theoretical prediction from the proposed kinetic model and the calculated reaction rate constants fit the experimental data well for different concentrations of hydrogen peroxide and a continuous treatment of 2-chlorophenol wastewater. By using this model and changing the operating conditions, different concentration of hydrogen peroxide and influent flow rate, one can predict and achieve the desired output concentration of 2-chlorophenol in the continuous photolytic hydrogen peroxide oxidation process.
