Abstract
Hemicellulose-based porous hydrogel for methylene blue adsorption from aqueous solution was studied. The surface morphology of sample was analyzed by SEM, finding that it had the porous structure. Effects of pH and initial concentration on the adsorption capacity were investigated. Isotherm studies found that the adsorption of metylene blue onto absorbent was a monolayer adsorption, and the maximum adsorption capacity was 444.44 mg/g. The adsorption mechanism was analyzed by FT-IR, and it showed that the produced -COO- groups in alkaline conditions were advantaged for adsorption process, which offers the impetus for combination of adsorbent and methylene blue. Hemicellulose-based porous hydrogel is an inexpensive and biodegradable material, and can be a promising absorbent for cationic removing from wastewater.Keywords
