Abstract:
Pesticides are applied widely to protect plants from disease, weeds and insect damage, and usually come into contact with soil and water. Therefore, the elimination of these materials is a good manner in view point of environment [1]. In this work, we modified bentonite with Fe 2+for Fenton reaction simulation. The photocatalyst was characterized using FT-IR, XRD, XRF, FESEM and EDX technique. The photocatalytic activity of this system was investigated in the removal of malathion and diazinone in the presence of H2O2 under UV irradiation. The effect of various parameter including catalyst amount, H2O2 concentration, pesticide concentration and time expose was studied. The COD experiment was performed for determination of degradation amount.
