Abstract

Introduction: Diazinon is an organophosphate pesticides that widely used for agricultural pests and vectors. Diazinon resists to biodegradation so there is major concern about it. The aim of present work was to study the decompostionof diazinon by nano-photocatalytic ZnO-TiO2 in the presence of UVC radiation. Materials and Methods: This work is a laboratory-experimental study. Characterization of nanoparticles was determined through TEM pattern. The number of samples was determined by Taguchi statistical method. The samples with definite concentration of diazinon and nanopartical in different operational conditions were exposed to UVC radiation, individually .Diazinon concentration was measured using HPLC. Data analysis was performed using the software Minitab 16. Results: The results showed that with increasing reaction time, the removal of diazinon increases but by increasingthe dose of nanoparticles and Diazinon concentration the removal rate decreases. The highest removal efficiency rate was 95%. Conclusion:  The combination of catalysts is a new method for the removal of diazinon. The results showed that the photocatalytic nano-ZnO-TiO2 has a positive effect on diazinon degradation
