Abstract
Methylene blue adsorption from aqueous solution onto activated carbon prepared from
strychnos potatorum seed was investigated under various experimental conditions. Batch mode
experiments and equilibrium isotherm studies were conducted to assess the potential of the above
activated carbon for the removal of Methylene blue from aqueous solution by varying the following three
parameters: initial concentration of Methylene blue dye solution, adsorbent dose on the uptake of dye
from the solution, and pH. The equilibrium data obtained were fitted to Langmuir and Freundlich isotherm
models.
