Biopolymers are sustainable, carbon neutrals and are always renewable. Starch is the second most abundant natural biopolymer on the earth. In order to improve the performance of starch, crosslinking is often carried out either in the processes of starch modification or during the application processes. By controlling the degree of crosslinking, the water retention capacity of starch-based hydrogel can be well controlled. In addition, the adsorptivity and binding strength of starch on a substrate can be significantly improved. Chemically modified biopolymers can be used as selective metal chelators. They have applications in waste water management. In the present study chemical crosslinking of starch using Ethanedial (glyoxal) was carried out to judge its adsorptivity towards Copper. The novel crosslinked biopolymer is characterized by IR, NMR, XRD. Surface chemistry of metal- biopolymer was studied using SEM. Copyright@ International Science Community Association
