外文摘要：In the present study, carboxymethyl-beta-cyclodextrin (CM-CD) molecules were introduced onto the surfaces of Fe3O4 nanoparticles via chemical co-precipitation approach. The synthesized Fe3O4/CM-CD composite exhibited high magnetism and could be easily separated from the aqueous phase by exposing to an external magnetic field. In addition, the composite was stable in solution over a wide pH range. The effects of contact time, solution pH, ionic strength, solid dosage and temperature on the removal performance of Fe3O4/CM-CD toward a cationic dye named C.I. Basic Blue 3 (BB3) were evaluated by using the batch technique. The sorption kinetic process achieved equilibrium within a contact time of 90 min. The sorption isotherm data were simulated by the Langmuir model well and the maximum sorption capacity was calculated to be 203.54 mg/g at 298 K. The Fe3O4/CM-CD composite exhibited favorable removal performance toward BB3 in both the single-solute system and the simulation effluent. After sorption equilibrium, the BB3-loaded composite could be easily regenerated and reused for multiple sorption/desorption cycles. The experimental findings herein proposed the feasibility of adopting Fe3O4/CM-CD composite for the decontamination of BB3 from the polluted water systems.
