Abstract

In this study, nano-scale crystalline alumina was synthesized on single walled carbon nanotube by sol-gel method for using as a sorbent For solid phase extraction of trace metals. The characterization of the synthesized nanocomposite material was performed by scanning electron microscope, transmission electron microscope and X-ray diffractometer methods. It was proved that the obtained composite material was mainly nano-scale Al2O3, and partly Mg2Al2O4 and Zn2Al2O4 on single walled carbon nanotube. In addition, the specific surface area of the material was determined and found as 165 m(2)/g. The adsorption capacity of the nanomaterial was also determined for cadmium(II) ions and found as 2.18 mg/g at pH 8.
