Application of chitinous products in waste water treatment has received considerable attention in recent years. The Chitosan, deacetylated chitin derivative is the most interesting biopolymer in the world of adsorption science.The preparation of chitosan beads and chitosan membranes were explained in this paper. The properties of chitosan flake, beads, and film was studied with different analytical method such as CHN, SEM, FTIR, DSC, etc. Chemical modification of chitosan membranes and beads were performed by crosslinking with glutaraldehyde and its properties were analysed.The Adsorption studies of Hg(II) ion was carried out in a batch process at room temperature in static manner with varying parameters such as pH of solution, adsorbent concentration and different Chitosan forms. Metal concentration was measured using ICP AES. It has been shown that cross linked chitosan beads have higher adsorption degree compared to chitosan flakes and cross linked chitosan membrane. The removal efficiency of cross linked chitosan beads on multi element solution shows that the maximum adsorption shown by Chromium (88.29%) followed by Cd > Cu > Ni > Ag > Pb > Zn
