Removal of Nickel (II), Copper (II) and Iron (III) from aqueous solutions using the adsorption process on Raatrani plant material has investigated. Physical, Chemical and Liquid phase adsorption, FT-IR characterization of Raatrani Leaf Powder (RLP) done by standard procedures studies on the removal of Ni (II), Cu (II) and Fe (III) ions were attempted by varying adsorbate dose, pH of the metal ion solution and time in batch mode. The equilibrium adsorption data were fitted with Freundlich, Langmuir Isotherms and the Isotherms constant were evaluated. A time variation study indicates that adsorption follows pseudo-first order kinetics. pH was found to have significant role to play in the adsorption. The processes were exothermic and the thermodynamic parameters were evaluated
