In the present study, the adsorption of benzene, toluene, ethylbenzene and metaxylene
(BTEX) from Diethanolamine (DEA) solution by commercial and granular activated
carbon (AC) were performed.The Langmuir, Freundlich and Sips isotherm models were
used to describe the equilibrium data. The accuracy of the results obtained from the
adsorption isotherm models was compared and the values for the regressed parameters
were reported. The results show that the sips isotherm has better agreement with the
experimental data for all AC samples in comparison with the other isotherms.According to
the adsorption isotherm curves obtained from experiments, the amount of adsorption of
metaxylene, ethylbenzene, toluene, benzene increases respectively.
