Adsorption of Congo Red on AB-8 Macroporous Resin

Abstract:

Waste water containing Congo red in industrial production has caused many serious environmental problems worldwide. In this paper, AB-8 macroporous resin was used to remove Congo red from an aqueous solution by adsorption technique under varying conditions of pH, adsorbent dosage, agitation time, temperature and initial concentration. The results show the adsorption kinetics is well described by pseudo-second-order model. It was found that the equilibrium data was better represented by the Freundlich isotherm model.
