中文摘要：

该文采用溶剂热法合成了不同微结构特性的磁性CoxCu（1-x）Fe2O4纳米吸附剂,通过透射电子显微镜（TEM）、X-射线衍射（XRD）、BET比表面积仪、磁强计等手段研究了材料的特性,并将此应用于水中五氯苯酚的吸附。结果表明,CoxCu（1-x）Fe2O4具有良好的吸附能力和磁性能。最合适的调控制备条件是Co含量（x）为0.5,处理温度为200℃。吸附剂对五氯苯酚的吸附符合Langergren一级动力学模型,平衡吸附量为21.55 mg/g;吸附等温线符合Freundlich模型。此外,CoxCu（1-x）Fe2O4具有良好磁性,容易回收,经O3再生处理,可重复使用。

英文摘要：

The different microstructure characteristics of magnetic CoxCu~xFe204 nano adsorbents were prepared by solvothermal method and characterized using the transmission electron microscopy （TEM）, X-ray diffraction（XRD）, BET （Brunauer-Emmett-Teller） specific surface area analyzer and a vibrating sample magnetometer. The CoxCu1-xe2O4 was employed as ad- sorbents 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-xe2O4 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-xe2O4 magnetic adsorbent, easy to recover and after 03 regeneration treatment can be reused.
