Heavy Metal Biosorption Using A Biopolymer Chitin

D. Saravanan, P. N. Sudha

Abstract :

In this study the low cost seafood processing wastes chitin was blended with bentonite with and without the presence of crosslinking agent and characterized using various analytical techniques (FTIR, DSC, TGA and XRD analysis), also binding of metals to polymers was investigated. The adsorption was studied by batch method. The influence of initial concentration, dosage of adsorbent, contact time and pH were experimentally verified. Adsorption studies were done on both cross–linked and non–crosslinked chitin for Cr(VI) and Cu(II) ion. The adsorption behavior could be described using the Langmuir and Freundlich isotherm, the thermodynamic and equiliium parameters of the reaction were determined to understand the sorption behavior of chitin blend. The results revealed that the adsorption of above metals by chitin blend is spontaneous, endothermic and favorable. Hence, the blended copolymer could open way for waste water treatment in industrial level. The cross linking agent incorporated into the polymer blends to improve the mechanical properties such as surface hardness, stiffness, resistance to temperature and solvent attack.
