Photocatalytic degradation of leachate using uv visible coupled with nanotechnologies

Abstract

newline Growing urbanization and manufacturing in developing countries result in the generation of substantial amounts of Municipal Solid Waste (MSW). The Final disposal of solid waste material, viz., sanitary landfill, composting, recycling or reuse, dumping into the sea, and incineration, has been adopted across the world. The sanitary landfill method is commonly employed, particulary in developing and underdeveloped countries. The generation of a highly toxic liquid occurs in a sanitary landfill area called leachate. The production of leachate poses a significant threat to the quality of groundwater in and around MSW dumpsites. Leachate samples are collected from the landfill at the Perungudi dumping yard, Chennai, Tamil Nadu.When compared to chemical and physical methods, Photocatalysis has attracted attention as a promising approach for the degradation of leachate water contaminants. Itindicated that UV-visible nanoparticles are affordable, reusable, efficient, and environmentally friendly.
