The effects of carbonization temperature on some
physicochemical properties of Bamboo waste by the chemical
activation with potassium hydroxide have been investigated.
The bamboo based activated carbon was characterized in terms of the yield rate, ash, porosity, density, and specific surface area at different carbonization temperature in the chemical activation process using standard methods of analysis. The results showed specific surface area, density, yield, moisture content porosity and ash content were 234m3/g, 0.483g/cm3, 32.67%, 0.74 and 2.92% respectively. The metal contents present were Pb2+, Fe2+, Ni2+, Zn2+,and Cd2+ with Z2n2+ having the highest concentration ( 31.40mg/kg) and Cd2+(8.9mg/kg), the lowest. The yield rate decreases with increase in temperature, while ash, density and specific surface area increases with increase in temperature. KOH activation of bamboo was suitable for the preparation of charcoal which are essentially microporous.
