SOLAR PHOTOCATALYTIC DEGRADATION OF ATRAZINE IN WATER BY A TiO{sub}2/AG NANOCOMPOSITE

摘要

One of the most common herbicides in the world, Atrazine, was used as a model pollutant in this study. The photocatalytic activities of the nanocomposite of TiO{sub}2/Ag, with nanopaticles of TiO{sub}2 and Ag, were investigated by photodegradation of atrazine under the natural sun. It was found that the efficiency of solar-photocatalytic activity was increased significantly by using the nanocomposites of TiO{sub}2/Ag, compared to the use of TiO{sub}2 alone. The mechanism of the TiO{sub}2/Ag composite for enhancement of photocatalytic activity was elucidated in this work.
