Abstract
The adsorption thermodynamic parameters, namely ÎadsH, ÎadsG, and ÎadsS, were determined for all the factorial design results. Endothermic values were found in relation to the ÎadsH. The positive ÎadsS values indicate that entropy is a driving force for adsorption. The ÎadsG values are also significantly affected by important antagonistic and synergistic effects involving all principal and interactive factors. It is concluded that the thermodynamical spontaneity of the IC adsorption parameters are greatly influenced by the interactive factors and not by the temperature changes alone.
