A Study on the Photocatalytic Degradation of Organophosphorous Pesticide Wastewater by the New Photocatalyst AgBr/TiO_2

摘要

In the experiment a new photocatalyst AgBr/TiO_2 was prepared by modifying TiO_2 and was applied to degrade the organophosphorous pesticide wastewater. Some factors influencing the degradation were discussed. The results showed that the AgBr/TiO_2 had higher photocatalytic activity; when the quality of photocatalyst was 1.2g, the initial concentration of the organophosphorous pesticide wastewater was 100mg/L, the PH was 11 and the degradation time was 100 minutes,the treatment effect of photocatalytic degradating organophosphorous pesticide wastewater was the best.
