Equilibrium adsorption of aniline, benzaldehyde, and benzoic acid on granular activated carbon (GAC) has been investigated. Experiments were carried out on two sizes of activated carbon. The equilibrium data were analyzed using the ordinary least square approach. The results show that the adsorption process was more effectively described by Hill and Koble-Corrigan isotherm models based on the values of the least square parameter, Durbin-Watson Test, and mean relative percent error. Furthermore…
