In this study, MWCNTs were used to investigate the removal of sodium dodecyl benzene sulfonate (SDBS) in industrial wastewater. The effect of pH, adsorbent dosage, dispersion time and temperature on the kinetics and equilibrium of SDBS sorption on MWCNTs were examined. Consistent with an endothermic reaction, an increase in the temperature resulted in a decreasing SDBS adsorption rate. The adsorption kinetic was well fitted by the pseudo second-order kinetic model. The adsorption isotherm data could be well described by the Freundlich equations. The results suggest that MWCNT could be employed as an efficient adsorbent for the removal of SDBS from aqueous media. aqueous media, multi-walled carbon nanotube, sodium dodecyl benzene sulfonate © IWA Publishing 2016 You do not currently have access to this content.
