摘要：
In order to increase added values of rubber wood, hydrogel was prepared using modified rubber wood cellulose as matrix for dye adsorption. Purified cellulose fibrils (PCF) separated from rubber wood was modified via carboxymethylation, and hydrogel was prepared by inverse suspension polymerization. The swelling properties of the hydrogel were studied in buffer solutions with different pH values and the adsorption of different concentration Rhodamine B (RhB) was investigated. The spherical hydrogel showed pH sensitivity and good RhB adsorption performance. RhB adsorption capacity is 546.81 mg∙g-1 when adding κ-carrageenan hydrogel in buffer solution of pH 10 and RhB concentration of 1 200 mg∙L-1, which indicates that the prepared spherical hydrogel has potential application in dye adsorption. © 2019, Editorial Board of "Journal of Chemical Engineering of Chinese Universities".
