Biosuperabsorbent polymers are obtained by the graft copolymerization of acrylic acid (AcA) and acrylonitrile(AN) monomers onto CMC, using Ceric ammonium nitrate as a free radical initiator in the presence of methylene bisacrylamide as a crosslinker. Graft Evidence of grafting was obtained by comparison of FTIR spectra of CMC and homopolymer-free H-CMC-g-poly(AcA-co-AN). The effect of the concentration of the initiator, monomers, polysaccharide and crosslinker as well as chemical-invironment parameters on the swelling amount of biosuperabsorbent were investigated to achieve the optimum absorbency. https://www.biotech-asia.org/vol8no2/investigation-of-effective-parameters-in-synthesis-of-biosuperabsorbent-hydrogel-based-on-carboxymethylcellulose/ CMC; hydrogel; Ceric ammonium nitrate; acrylic monomers; optimization
