The adsorption equilibria of phenol and chloroform from aqueous solutions on four different particle sizes of activated charcoal were examined at different initial concentrations of the adsorbates. The experimental data were analyzed using the Langmuir and Freundlich isotherm models. Both models fit the adsorption data for phenol. The Freundlich model more accurately fits the adsorption data for chloroform than the Langmuir model. The sorption kinetics for phenol was studied using pseudo-first-order and second-order kinetic models. The adsorption data better fit the second-order model. The results of the study show that activated charcoal can be used as potential adsorbent for phenol and chloroform in drinking water.
