dc.description.abstractIn the present study, the decomposition of diazinon by O-3, O-3/UV, and O-3/UV/H2O2 processes was studied. Diazinon and its oxidation by-product, diazoxon, were identified using gas chromatography/mass spectrometry (GC-MS). Chemical oxidation of diazinon in aqueous solution by ozonation was studied under various solution pH values and 03 concentrations. Acidic and alkaline solutions accelerated diazinon degradation, and complete mineralization of diazinon was achieved in 30 min at pH 9.0. Diazinon removal increased with ozone dosage, however, 2.0 mg L-1 of ozone with 30 min oxidation time was more economical and efficient. O-3/UV/H2O2 combination enhanced decomposition of both diazinon and diazoxon due to the reaction between analytes and hydroxyl radicals. Toxicity measurements of the treated solutions were carried out in order to evaluate the efficiency of the treatment methods. The present study validated that O-3/UV/H2O2 combination is a feasible process for the removal of the tested pesticide from aqueous solutions.en_US
