A Mathematical Model for Adsorption of Surfactant onto Powdered Activated Carbon

The main objectives of this study were to remove surface-active agents and to predict the adsorption rejection models. The effects of surfactant concentration and PAC amount on the adsorption were determined. For both surfactants, It was found that the adsorption values also increased when PAC amount increased. It was observed that the rejection values are different for the adsorption of CTAB and LABS. In addition, new rejection models are proposed to be able to estimate the rejection of surfactants depending on surfactant concentration and PAC amount. The results indicated that model predictions were in accordance with the experimental data.
