The effect of anode dust concentration on removal efficiency of Cr(VI) and Ni(II) ions from aqueous solution by adsorption

The examined adsorbent is anode dust known as a solid residue and waste material from aluminium production. The effect of adsorbent concentration on the removal efficiency of Cr (VI) and Ni (II) ions was investigated. The results obtained show that removal efficiency is strongly dependent on adsorbent concentration. The values indicate that the removal efficiency of Cr (VI) and Ni (II) ions from aqueous solutions increases to the optimum concentration of adsorbent and then slowly decreases. The most successful removal of Cr (VI) and Ni (II) ions is achieved with adsorbent concentration of 15 g/l.
