Development of Novel Photocatalytic Materials and Surfaces for Environmental Clean-up
(2011-10-03T08:43:26Z) Surolia, Praveen Kumar
During the past several decades, the growth of population and the activities in industries and agriculture have significantly altered the environment and reduced the availability of natural resources. Moreover, some of the activities results in persistent and toxic organic substrates and hazardous wastes as pollutants in wastewater effluent, underground storage tanks and dump sites of industrial manufacture. Typical wastes of concern include volatile organics, chlorinated volatile organics, dioxins, dibenzofurans, pesticides, nitro-aromatic compounds, PCB's, chlorophenols, asbestos, heavy metals, arsenic compounds, aviation fuel, solvents, and degreasing agents. Due to disposal of these chemicals, the surrounding soil and underlying groundwater aquifers have become contaminated resulting into lot of stress on the availability of fresh water. Therefore, the control of chemical pollutants has received much attention. The removal of the pollutants by complete mineralization of a wide range of chemical compounds has become relevant and important. Innovative water and wastewater technologies are needed to meet the challenges of deterioration of water quality
