Abstract

Activated carbons were thermally prepared from Hura Crepitan L. seed shells. Zinc chloride (ZnCl2) and phosphoric acid (H3PO4) were separately used as the activating agents. The activated carbons obtained were characterized by determining the percentage yield, moisture content, ash content and percentage fixed carbon. The adsorption of methylene blue by the activated carbon was done using 0.1 to 0.5 g of the activated carbon. The results revealed that the percentage yield and ash content of H3PO4 impregnated activated carbon was higher than ZnCl2 impregnated activated carbon. On the other hand, ZnCl2 impregnated activated carbon had higher moisture content and percentage fixed carbon. It was also revealed that ZnCl2 impregnated activated carbon had greater adsorption capacity than H3PO4 impregnated activated carbon. However, it was found that the higher the adsorbent (activated carbon) dosage, the higher the adsorption capacity.

 

Key words: Hura Crepitan L., activation, activated carbon, zinc chloride and phosphoric acid.
