PHOTOCATALYTIC DEGRADATION OF WASTE WATER ON THIN FILMS OF TiO_2

摘要

The degradation of organic phosphorous pesticide waste water using thin films of TiO_2, which was prepared in an atmospheric vertical chemical vapor deposition system, was studied, The results show that the wafer material for coating TiO_2, the photocatalytic time, the TiO_2 crystal phase, the pH value and the concentration of pesticides in waste water influence the degradation rate. These facts indicate some potential for photocatalytic treatment of waste water by utilizing sunlight.
