Abstrakt: A new environmental-friendly magnetic cellulosic adsorbent MnFe2O4@Cel-g-p(AA-DMC) was easily synthesized via natural cellulose and easy-recovered magnetic particles MnFe2O4. Magnetic cellulose composites were characterized by SEM, TEM, XPS, XRD, BET, VSM, TGA and FTIR. The effect of pH, contact time and PMS dosage on adsorption was investigated. Besides, the adsorption kinetic model was well-fitted to the pseudo-second-order model, and the adsorption isotherm were matched with the Frenudlich isotherm model. The MnFe2O4@Cel-g-p(AA-DMC) posseses the excellent stability, reusability and superior superparamagnetic behavior and its possible adsorption mechanism for the adsorption of CR was proposed.
