Innovations in the development of novel technologies for wastewater treatment are very promising. Additionally, advances in nanoscale science and engineering suggest that many of the current problems involving water quality could be resolved or greatly alleviated using novel materials, such as nanosorbents or nanocatalysts. Nanotechnology-derived products that reduce to very low levels or even totally destruct toxic and hazardous compounds can assist in the attainment of water quality standards and health advisories. This project uses novel TiO2 nanoparticles for water treatment under UV irradiation. Emphasis is given on the removal of emerging micro-pollutants, such as Bisphenol A (BPA).
