Enhanced Removal of Cationic Dye Methylene Blue from Aqueous Solution Using Nanocellulose Prepared from Agricultural Waste Sugarcane Bagasse

In the present communication nanocellulose was prepared from agricultural waste sugarcane bagasse and used for the removal of cationic dye methylene blue. Nanocellulose was prepared using bleaching treatment of agricultural waste followed by acid hydrolysis. SEM, TEM and TGA techniques were used to characterize prepared nanocellulose particles. Adsorption studies were optimized using simple batch experiments. Maximum sorption efficiency obtained for the removal of methylene blue using nanocellulose is 35 mg/g. The adsorption process fitted well for both Langmuir and freundlich isotherms. Regeneration studies signify that nanocellulose can be used successively up to 6 cycles of adsorption/desorption.
