Abstract:
In this work, rice husk waste was used as a precursor for the production of a low-cost
activated carbon (AC) with phosphoric acid chemical activation. The effects of the
production variables, such as impregnation ratio, activation temperature and activation time
were investigated. The optimal activated carbon which had the highest surface area was
obtained by these conditions as follows: 30% phosphoric acid solution, 600 °C activation
temperature and 60 min activation time. The obtained activated carbon was then employed
for the adsorption of dye (Acridine Orange) and it was found that activated carbon exhibited
the highest adsorption capability. The experimental results were analyzed using Freundlich
and Langmuir isotherm models. Moreover, the equilibrium data were fitted into different
adsorption isotherm and found to fit well with Freundlich model with a maximum monolayer
adsorption capability of 476.2 mg/g, whereas the adsorption kinetics followed the pseudosecond-
order kinetics. It is inferred from the experimental result that the activated carbons
from agricultural wastes can be applied as an adsorbent substitute to commercial activated
carbon (CAC) in the removal of Acridine Orange from waste water.
