Microporous activated carbons with high surface area are of great interest for the remediation of textile wastewater in a sustainable manner. An activated carbon prepared from Euphorbia antiquorum L (EAC) was impregnated with Polyvinyl alcohol solution to provide mechanical stability and increase the abrasion resistance. The surface area of EAC and PVAC were 918 and 713.8 m2/g respectively. An adsorption characteristic of the Polyvinyl Alcohol Supported Activated Carbon (PVAC) was analyzed with the help of pseudo first order and second order kinetic models.

Extreme wave events of 1000 and 1500 years (radiocarbon ages) have been recently reported in Mahabalipuram region, southeast coast of India. Subsequently, we carried out extensive sedimentological analysis in regions covering a total lateral coverage of 12 km with a new archeological site as the central portion of the study area.
