Studies on the removal of copper by adsorption on modified sand have been investigated. The adsorbentwas characterized by XRD, FTIR and SEM. Removal of Cu was carried out in batch mode. The values ofthermodynamic parameters namely DG0, DH0 and DS0 at 25℃ were found to be -0.230 kcal-1 mol-1,+4.73 kcal-1 mol-1 and +16.646 cal K-1 mol-1, respectively. The process of removal was governed bypseudo second order rate equation and value of k2 was found to be 0.122 g mg-1 min-1 at 25℃. Theresultant data can serve as baseline data for designing treatment plants at industrial scale.
