Characterization Of Activated Carbon Prepared From Coconut Shell Using Various Reagents For A Low Cost Water- Filter

Abstract

The chemical and physical conditions used in the preparation of activated carbon, an adsorbent used in water filtration, influence the specific surface area and porosity. In this paper, coconut shell was the raw material and activation reagents such as Hydrochloric acid, Zinc Chloride and Phosphoric Acid were used. A single burn and double burn process was carried out for each method. The activated carbon obtained was compared in terms of absorption capacity, bulk density, BET specific surface are a and pore volume. The best results were yielded fo r activated carbon prepared using phosphoric acid with the single burn technique.
