Preparation and characterization of activated carbons from rice husks and shells of palm fruits

Preparation and Characterization of High Surface Area Activated Carbons from Palm Shells Suitable for Adsorption of Higher Molecular Weight Compounds

1 Monash University, Sunway Campus, Malaysia * The Petroleum Institute, Abudhabi, UAE Introduction Utilization of biomass for production of porous carbons is well established industrially, as the demand is abundant due to varied industrial application. Activated carbons with highly developed surface area are widely used in a variety of industries for applications which include separation/purifi...

Preparation, characterization and phenol adsorption capacity of activated carbons from African beech wood sawdust

In the present study, different activated carbons were prepared from carbonized African beech wood sawdust by potassium hydroxide activation. The activated carbons were characterized by brunauer–emmett–teller, scanning electron microscope, fourier transform infrared spectroscopy, and thermogravimetric analyzer. The phenol adsorption capacity of the prepared carbons was evaluated. The d...

Removal of Heavy Metal Ions with Acid Activated Carbons Derived from Oil Palm and Coconut Shells

In this work, batch adsorption experiments were carried out to investigate the suitability of prepared acid activated carbons in removing heavy metal ions such as nickel(II), lead(II) and chromium(VI). Acid activated carbons were obtained from oil palm and coconut shells using phosphoric acid under similar activation process while the differences lie either in impregnation condition or in both ...
