| Abstract: | The photocatalytic degradation of phosphate ester pesticides using TiO2/beads as a photocatalyst was studied. The results showed that the photocatalytic degradation reaction of the phosphate ester pesticides followed the first order kinetics, with 4 0×10-4 mol/L of dichlorvos and monocrotophos, the residual amount was lower than 10% after 1.5 h irradiation with a 375 W medium pressure mercury lamp, and the organophosphorous can be completely photocatalytically degraded into PO43- after 3.5 h irradiation. |
