In this study, Cross linked Chitosan (CCS) has been synthesized by anchoring a bi-functional Ligand, namely Pyridine-2, 6-Dicarboxylic acid (PDC) with chitosan through ion exchange. The functionalized biopolymer was characterized by elemental analysis (CHN), spectral (UV visible, FTIR and solid state 13C NMR), thermal (TGA and DSC), structural (powder XRD), surface and morphological (BET and SEM) analyses. The PDC-CCS was employed to adsorb Cu (II) ion from aqueous solutions. The influences of various operating parameters such as PH, temperature, initial concentration of Cu (II) ion and contact time on the adsorption capacity of PDC-CCS have been investigated
