Nanocomposites of magnetic attapulgite-resin (MPR) were prepared for adsorption of humic acid (HA). This nano adsorbent was characterized by X-ray diffractometer (XRD), Fourier Transform Infrared (FTIR) spectroscopy and Scanning Electron Microscope (SEM). The adsorption property of HA onto MPR was investigated. Experimental results indicated that MPR prepared by the ultrasonic dispersion exhibited a much better adsorption capacity than that of the resin and attapulgite. The effective specific surface area of the MPR was illustrated to be 674. 31 m(2)/g. With a initial concentration of HA of 14. 87 mg/L, the adsorption capacity reached 13 mg/g. Besides, it was found that the adsorption capacity increased with the contact time, and it reached the equilibrium at 233 min. The adsorption kinetics and isotherms could be well described by pseudo-second-order model and Langmuir isotherm model, respectively. Thermodynamic parameters (Delta H-theta, Delta S-theta, and Delta G(theta)) indicated that the adsorption was spontaneous and exothermic. Acetic acid had obvious influence on the adsorption of HA on this complex resin. The adsorbent could be reused six times without obvious decrease of adsorption performance.
