Title

Reactive Red 120 dye removal from aqueous solution by adsorption on nano-alumina

English Abstract

The adsorption of Reactive Red 120 dye from aqueous solutions by using nano-alumina has been investigated. The batch adsorption studies were carried out to determine the impact of pH, contact time, concentration of dye, and the adsorbent dose on adsorption process. The maximum adsorption efficiency was observed at pH 3. However with an increase of the adsorbent dose, the dye removal efficiency increased, while the amount of dye adsorbed per unit mass (mg/g) decreased. A pseudo-second-order model best described the adsorption kinetics of the specified dye onto nano-alumina. In this case the Langmuir isotherm model appeared to be most suitable. Findings of the present study reveal that nano-alumina can be an effective adsorbent for the removal of Reactive Red 120 from aqueous solutions.
