title: Oxidation of acetyl-pyrimidine wastewater by Fenton process.
abstract: In this study, contaminant degradation, priority performance, intermediates, and kinetics in catalytic oxidation of Acetyl-Pyrimidine wastewater by Fenton reagent were investigated. In batch experiments, the main parameters that govern the complex reactive system, i.e. temperature, pH, Fe²+, and H₂O₂ initial concentrations have been studied. The results showed total COD and Acetyl-Pyrimidine removal was above 50% and 90% respectively under the following oxidation conditions: T at 25 °C, pH at 3.5, H₂O₂ at 300 mmol/l, Fe²+ at 40 mmol/l, with the reaction time 2 h. Control experiment and UV-Infrared spectrums analysis indicated that Acetyl-Pyrimidine was removed prior to the small molecule organic. The reaction fit to a first-order rate equation and the activation energy of Pyrimidine was 2.365 kJ/mol.
