Bamboo, an abundant and inexpensive natural resource in Malaysia was used to prepare activated carbon by physiochemical activation with potassium hydroxide (KOH) and carbon dioxide (CO 2) as the activating agents at 850 °C for 2 h. The adsorption equilibrium and kinetics of methylene blue dye on suc...
