N2 - Degradation of the diazinon pesticide by photocatalytic ozonation under visible-light irradiation using C,N-codoped TiO2 as a catalyst was investigated. Effects of initial pH, initial concentration of diazinon, and energy sources on the degradation process were studied. The combination of photocatalysis and ozonation processes can lead to the effective degradation of diazinon in comparison to every one of the individual processes. The degradation percent-age obtained from the photocatalytic ozonation of 18 mg L-1 diazinon was 98 % and the COD removal reached 70 % after 25 minutes irradiation. The diazinon was transformed to less toxic compounds. Based on the results obtained, the photocatalytic ozonation is a potential process to treat wastewater containing the pesticide diazinon.
