Xylenol Orange Sorption on Modified Carboxymethyl Cellulose

Abstract

Modified carboxymethyl cellulose with β-cyclodextrin (CMC-β-CDP) was prepared and the sorption properties of CMC-β-CDP towards xylenol orange (XO) were investigated. Studies concerning the effects of contact time, sorption temperature and initial XO concentration were discussed. Results of batch experiments showed that CMC-β-CDP exhibited some sorption capacities towards XO. The isotherm fitted Freundlich model for the sorption of XO on CMC-β-CDP. The sorption capacities of CMC-β-CDP, β-cyclodextrin polymer (β-CDP) and carboxymethyl cellulose (CMC) towards XO in aqueous solutions were investigated. Results of contrast experiments showed that the sorption capacity of CMC-β-CDP for XO was higher than that of CMC and β-CDP.
