The potential harmful environmental implications of pharmaceuticals and personal care products (PPCP's) continue to worry scientists. Although the specific effects of these compounds are not entirely identified, water treatment processes have to be employed to ensure water quality. Removal of PPCP's from wastewater of drinking water requires advanced oxidation processes, such as ozonation and activated titanium dioxide (TiO2). This proposal investigates the impact UV activated TiO2may have on the degradation of common PPCP's like caffeine and aspirin. In addition, the treatise examines the degradation of natural organic matter by UV activated TiO2. The TiO2 catalyst will be added to the water and exposed to UV activation with samples of the water taken periodically and tested to determine a variety of water quality parameters including total organic carbon and color. All tests are performed in accordance with the Standards Methods for the Examination of Water and Wastewater 21st Edition manual. This project seeks to determine the effectiveness of titanium dioxide photocatalysis in the treatment of Alaska waters.
