| Abstract Scope |
Nigeria bentonite clay was modified using the template-free technique. Clay ore was thermally activated at 750 °C. The activated clay was reacted in 4 mol/L NaOH for 20 minutes at 80 °C. The activated bentonite was later reacted with 4 mol/L HCl for 2h at 100 °C. The dispersion was dried to give the mesoporous silica. The product was characterized by X-ray diffraction, energy dispersive, transmission microscopy and Nitrogen-gas adsorption. The result revealed the collapse of interlayer spaces with structural changes in the width and intensity of the smectite phase. The product is composed mainly of silicon, oxygen and aluminium. The pore size distribution shows a narrow pore size distribution centered at 4.23 with surface area at 158.40m2/g and the product was used in decolorization of waste engine oil with decolorization efficiency reaching 66.08%. The study showed material can be an economical and eco-friendly adsorbent in the treatment of pollutants. |
