Abstract
Herein, the Fe-Cu-ZnO nanocomposites with superior adsorption property and short contact time were prepared by a sol-gel method. The structural characterizations were analyzed via several analytical techniques including X-ray powder diffraction (XRD), the surface area and pore distribution (BET) method, scanning electron microscopy (SEM), Energy Dispersive X-ray Spectrometer (EDX) and Thermogravimetric analysis (TGA). It was found that the nanocomposite with a diameter of 18nm and surface area of 63 m(2)/g. The adsorption of dye model was fitted well with Langmuir model and the adsorption capacity was 77.7 mg.g(-1) at room temperature. The kinetics of adsorption rate of the indigo carmine was very fast, and fitted with a pseudo second order.
