%X Titanium dioxide sol was synthesized by sol-gel method with adulteration of Fe(NO_3)_3·9H_2O. The samples were characterized by XRD, DTA-TG and UV-Vis. The results show that the diameter of particles is 17.5 nm and pure anatase. From the UV-Vis spectra the absorption edge of iron-doped titania has a red shift and the absorption intensities are increased. The degradation rate of omethoate reaches 85.23% when the dosage of photocatalyst is optimally 0.2 g/L, pH=8.6 and 2.5 h illumination with high-voltage mercury lamp. The photocatalytic degradation kinetics follows the pseudo-first order reaction.
