The kinetics and mechanism of photo-oxidation of acrylonitrile and acetonitrile with hydrogen peroxide and ozone in wastewater

The study presents three types of Advanced Oxidation Processes , Ozone with UV, Ozone with Hydrogen Peroxide in the presence of UV, Various Hydrogen peroxide dosages and PH levels in the presence of UV. A reaction kinetic model was proposed. The reaction rate constants and mass transfer coefficients are determined by a series of experiments and the use of the Rosenbrock Hillclimb Optimization Algorithm in conjuction with the Fourth ¬Order Runge - Kutta method on a digital computer. Experimental results indicated that the Hydrogen peroxide with UV at low PH level has been proven more effective for the treatment of acrylonitrile, acetoni-trile - containing wastewater, and Ozone with Hydrogen Peroxide in the presence of UV light has a significant accelerating effect on the rate of oxidation of acry-lonitrile, acetonitrile to enhance Ozone with UV process
