Abstract:

The ternary blends consisting of chitosan (CS)/Sodium alginate(SA)/Polyethylene glycol(PEG) were preapared by solution blending method. Chitosan was studied as a potential biosorbent due to its positive charge and relatively low cost. Sodium Alginate features are formability, hydrophilicity, biocompatibility, biodegradability, and exhibits high activity with the carbonyl and hydrogen groups on the chain. Polyethylene glycol (PEG), a linear or branched polyether, is formed through ring-opening polymerization of ethylene oxide. Blends of synthetic and natural polymers represent a new class of materials and have attracted much attention, especially in bio-application as biomaterial. The study involves evaluating the metal binding performance of chitosan/sodium alginate/polyethylene glycol using chromium aqueous solution. The characterization of the prepared sample was carried out using analytic techniques. The Intermolucular interactions were determined by Fourier Transform infrared and Crystalline nature of the prepared ternary blend determined by X-ray Diffraction studies. Thermal studies were carried out using TGA and DSC. Morphology of the Chitosan/ Sodium Alginate/ Polyethylene glycol ternary blends were observed using SEM studies. The blend shows significant effect on Adsorption models.
