Abstract

A carboxymethyl cellulose-g-(methyl methacrylate-co-acrylamide) was prepared from Sugarcane bagasse. The physical properties (e.g., degree of swelling, water desorption and gel content) of hydrogels were determined. FTIR analysis showed that the characteristic absorption band of MMA and AAM repeating units appeared in the spectra of the product and that confirmed the grafting of MMA and AAM monomers onto the CMC backbone. The maximum water absorption capacity of the prepared hydrogels was 50g/g in deionized water. The surface morphology of newly synthesized hydrogels was also identified by SEM. TGA, XRD, biodegradable properties and metal ions uptake of hydrogels were also investigated. The result ensures that the prepared hydrogel can be effectively used in personal absorbent products, biomedical applications, and polluted water treatment.
