The solid phase grafting product methyl methacrylate grafting sugarcane bagasse (SCB-g-MMA) was prepared by the methyl methacrylate (MMA) grafted sugarcane bagasse (SCB) surface after alkali treatment through solid phase grafting method. And its structure was characterized and analyzed by XRD, FTIR, 13C NMR, SEM and Brunauer-Emmett-Teller (BET) methods etc. Then the SCB-g-MMA was applied to adsorb methylene blue (MB) and adsorption property investigation was carried out. The results show that when the initial concentration of MB is 50-400 mg/L, pH value of aqueous solution is 6-12, dosage of adsorbent is more than 10 g/L and adsorption time is more than 40 min, the removal efficiency of MB by SCB-g-MMA is 99% at room temperature. And when the dosage of adsorbent is 2.5 g/L, the adsorption capacity of MB is 97.3 mg/g. In addition, the adsorption kinetics and the adsorption isotherm of SCB-g-MMA for MB are more fitted to the pseudo-second-order kinetic equation and Freundlich isotherm adsorption model, respectively.
