Abstract：The different microstructure characteristics of magnetic CoxCu1-xFe2O4 nano adsorbents were prepared by solvothermal method and characterized using the transmission electron microscopy (TEM),X-ray diffraction(XRD),BET (BrunauerEmmett-Teller) specific surface area analyzer and a vibrating sample magnetometer.The CoxCu1-xFe2O4 was employed as adsorbents for pentachlorophenol,and the results indicated that CoxCu1-xFe2O4 adsorbent has good adsorption characteristics and magnetic property.The suitable conditions were Co content (x) as 0.5,and the treatment temperature as 200 ℃.Adsorption experiments indicated that the adsorption kinetics curves of pentachlorophenol(PCP)on CoxCu1-xFe2O4 could be well correlated by Langergren kinetic adsorption model and the equilibrium adsorption capacity was 21.55 mg/g.The adsorption isotherms for PCP could be well correlated by Freundlich model.In addition,the CoxCu1-xfe2O4 magnetic adsorbent,easy to recover and after O3 regeneration treatment can be reused.
