Abstract

Introduction: A variety of pesticides is used to combat weeds. Check-resistant residues of contaminants in drinking water resources have detrimental effects on human health and on

environment. In recent years, advanced oxidation methods o remove toxins from the environment, particularly the aquatic environment is further considered.

Methods: In this study, samples adding different concentrations (mg/L10, 20, 30) of pesticides were prepared in deionized water. Specimens of the individual phases in a batch reactor with the catalyst (g / L 1,2, 3 and, 4), pH (3,5, 7, 9, 11) and contact time (60, 120, 180, 240 min) exposure contacts coupled Ag / ZnO and UV-c was performed.

Results: The results showed a reduction in pesticide concentrations (2, 4-D) and increasing the reaction time, the degradation efficiency increases. The highest degradation efficiency was for 240 minutes and the initial concentration of toxin was (2, 4-D) 10 mg/L to 96 percent. The kinetics of the elimination of toxins (2, 4-D) by the process of photocatalytic Ag / ZnO in the presence of UV-C light corresponded to the pseudo first.

Conclusion: The most effective degradation of toxins (2, 4-D) by the process of photocatalytic Ag / ZnO under conditions of neutral pH and with increasing reaction time and reduce toxin concentrations (2, 4-D) is the result.
