Abstract
The present work focused on the synthesis and characterization of cobalt ferrite (CoFe2O4) on expanded graphite (EG) via a simple sol-gel auto-combustion route for the removal of oil leakage. The morphological, structural, and surface charge properties of the calcined nanocomposites were determined by Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Energy dispersion X-ray analysis (EDX). Magnetic properties such as the magnetic saturation, coercivity and remanence were measured by a vibrating sample magnetometer (VSM) at room temperature, which presented that the expanded graphite and CoFe2O4 based composite exhibited typical magnetic behaviors. This research objective is to investigate the adsorption capacity of the magnetic CoFe2O4 decorated expanded graphite (EG-CoFe2O4) for diesel oil (DO), crude oil (CO) and fuel oil (FO) in water environment.
