Abstract:Novel lignosulfonate sodium graft 2-acrylamido-2-methylpropanesulfonicacid and acrylic acid and attapulgite (LS-g-P AA / AMPS /APT) biomass resin adsorption was synthesized by grafting polymerization using microwave irradiation.The chemical micstructure of resin was determined by means of FTIR and XRD .The effects of adsorbent dosage,the solution pH, concentration of the dye and the adsorption time and temperature on adsorption process for methylene blue (MB) were studied. The results shows that under the conditions of adsorbent dosage of 0.1g,the dye concentration of 500mg/L and the volume of 200mL,the adsorption capacity and removal was found to be 968 mg/g and 96%, respectively. The resin has strong pH sensitivity and high adsorption capacity.The equilibrium data were fitted to the Freundlich isotherm. The adsorption process of MB onto resin can be described with the pseudo-second-order kinetic model,indicating that the adsorption process is mainly endothermic chemisorption.
