Abstract :
The adsorption and desorption properties of beta-cyclodextrin polymer (beta-CDP) for 4-cresol were investigated. Studies concerning the effects of pH, contact time and initial 4-cresol concentration were presented and discussed. Results of batch experiments showed that this adsorbent exhibited some sorption capacities toward 4-cresol. It was found that kinetics followed a Ho and McKay equation and isotherm fitted Freundlich model for the adsorption of 4-cresol on beta-CDP. The regeneration capacity of beta-CDP was so strong that it could be used as a kind of recyclable adsorbent.
