Adsorption of Zn(II) Ions on Metallurgical Waste

Abstract

Metallurgical waste has great potential for use as an adsorbent for the removal of heavy metals from wastewater, standing out as possible low-cost adsorbents. This article presents the adsorption behaviour of Zn(II) ions on two solid metal waste materials – waste mould sand (WMS) and anode dust (AD). The obtained results showed that both waste materials could be used as potential adsorbents. Anode dust has better adsorption properties. The equilibrium data for the adsorption of Zn(II) on waste metallurgical materials were examined by Langmuir and Freundlich’s adsorption isotherm models. It was found that the Langmuir model is more appropriate, and that adsorption takes place as chemisorption.
