WATER DETOXIFICATION AND DISINFECTION USING HIGH SOLAR CONCENTRATION AND HOMOGENEOUS PHOTOCATALYSTS

摘要: The objectives of the research were to explore use concentrated sunlight combined with dissolved photocatalysts improve water quality. Initial experiments bromacil using organic-dye photosensitizers indicated that reaction kinetics enhanced by light. Other pesticides (EPTC, Tribufos, Atrazine and Lindane) also tested in normal sunlight. Organic dyes effective degrading some these compounds but did not appear be promising for complete mineralization. For most target compounds, rates approximately proportional intensity Iron especially combination hydrogen peroxide as oxidizer, proved all pesticides. This system was shown mineralize phenol. Reaction again intensity. photoefficiency this a range high enough indicate visible light, well UV, participating photo-reactions. Preliminary disinfection tests have either organic or iron are effective. It is concluded from work solar irradiation iron-peroxide promising, possibly low cost, means improving
