Degradation of Pesticide by Photo-catalysis with Titanium Dioxide Thin Films
|
Abstract:
The feasibility study on degradation of organic phosphorous pesticide by photo-catalysis at the surface of titanium dioxide thin films was carried out. The films were prepared over different substrates by lower pressurechemical vapor deposition. The factors influencing the degradation rate of organic phosphorous pesticide were investigated. It was found that the optimal conditions for photo-catalytic conversion are copper wire as the substrate, annealing the film at 450oC and using the film as quickly as possible after it is deposited. It is also shown that when the pH of solution is equal to 2 and nitric acid is used to adjust pH, the degradation conversion is higher.
