Textural and chemical characterization of activated carbons prepared from rice husk (Oryza Sativa) using a two-stage activation process

Activated carbons from agro-industrial wastes; rice husk; were prepared by physical and chemical activation using phosphoric acid as the dehydrating agent. A two-stage activation process method was used; with semi-carbonisation stage at 200oC for 15 minutes as the first stage followed by an...
