Abstract

A graft copolymer gel composite made up of locust bean gum (LBG), diallyldimethylammonium chloride (DADMAC), 2-acrylamido-2- methyl-1-propane sulfonic acid (AMPS) and bentonite (BNT) was prepared using methylenebisacrylamide (MBA) as crosslinker via microwave irradiation and characterised using FTIR, FESEM/EDS and XRD techniques. The graft ted copolymer composite was evaluated for its adsorption towards methylene blue (MB) dye. The LBG-g-poly (DADMAC-co-AMPS)/BNT showed a maximum adsorption of 70.89 mg/g compared to 65.09 mg/g showed by LBG-g-poly (DADMAC-co-AMPS). The adsorption data were subjected to two different isotherm models namely; Freundlich and Langmuir and were observed to be explained best by the Freundlich model. The adsorption of MB on the graft copolymer gel and the composite is observed to be a second-order kinetic process.
