%X TiO2 catalysts adhered to the glass were used for investigating photocatalytic degradation of pesticide imidacloprid in aqueous solution under 3×8W fluorescent lamps.The results showed that the photocatalytic degradation rate of imidacloprid was high and up to above 50%.And the photolysis fit a first-order kinetic relationship well.The photolysis rate constant of imidacloprid decreased with increasing initial concentration,which was explained by two mechanisms of photocatalytic degradation.By contrast,adherent TiO2 films with adding Carboxymethyl Cellulose-Na to treat was not easy to take off and the catalytic activity would not drop.In addition,the feasibility the imidacloprid photocatalytic degradation under the sunlight was also studied.
