Biological macromolecule chitosan grafted co-polymeric composite: bio-adsorption probe on cationic dyes

Abstract Chitosan biological macromolecule is a versatile polymer; chemical modification has been carried out that lead to the formation of chitosan grafted polymers composites (Chito-g-PC). We proposed synthesis six various Chito-g-PC as sorbents for toxic dyes. A novel graft copolymerization method based on radical polymerization with vinyl monomer like acrylic acid, acrylamide, N -isopropylacrylamide, methacrylic acid and polyacrylonitrile were utilized in order address large amount swelling at four different pH buffers solution. The effect initiator concentration, time temperature % grafting efficiency performed. Comparative characterization Chito evaluated by SEM, XRD FTIR, well solubility characteristics determined buffer Cationic dyes Malachite green (MG) Methylene blue (MB) selected sorbet, used biosorbents. Thermodynamic analysis showed sorption process was spontaneous endothermic an increased randomness. experiments realized MG MB pH.
