Activated carbon was produced from palm-kernel
shell using NaOH and KOH solutions as the activating agents.
The same was tested to determine its adsorptive capacity and
efficiency using methylene blue solution. Particle sizes of the
produced carbon were in the range of 600 – 2000 μm. The
adsorption process was carried out at two different temperatures
using methylene blue as adsorbate. It was observed that
adsorption of methylene blue dye using carbon activated
impregnated with KOH gave better result than with NaOH.
Based on the adsorption parameters obtained, the process was
found to be better described by the Freundlich adsorption
isotherm
