Preparation and characterization of activated carbon derived from rubber wood sawdust (Heavea Brasiliensis): textural and chemical characterization (Part 1)

Activated carbons from rubber wood sawdust (RW) were prepared by physical and chemical activation using potassium hydroxide as the dehydrating agent. A two-stage activation process method was used; with semi-carbonization stage at 200°C for 15 minutes as the first stage followed by an activation sta...
