2A Nanostructured materials for environmental remediation F. Lopez, G. Bufalo a , A. Ceglie, and L. Ambrosone a Department of Naples, ISPESL, via Lo monaco 3, 80121 Naples, Italy Aims The Environmental Remediation Project focused on characterization, monitoring, and modeling of subsurface environments, with a particular emphasis on contaminant remediation and water resources. The project is both basic and applied, and include studies that span a wide range of spatial scales (molecular studies to full-scale field investigations) and environmental conditions, and that employ expertise in various disciplines. Results Groundwater pollution is the loss of water quality due to waste products or others substances which alter the chemical and microbiological water properties. Traditional pump-and-treat techniques are very expensive and in the recent years considerable attention has been addressed towards the development of alternative technologies, such as surfactant-enhanced aquifer remediation. In this research project the micellare solubilizatio of 2,4,5 trichlorophenol was sphectrophotometrically investigated and the results was used as a model of chlorinated contaminant. With precipitating the excess of pollutant solubilized in SDS-micelles a novel surfactant-based adsorbent material was obtained 1 . The adsorptive efficiency of this novel material was tested through a cocurrent multistage process and its performance was compared with those of most known adsorbents such as activated carbon and silica gel.
