Abstract
The adsorption studies on the removal of Cr (VI) and Ni (II) ions from aqueous solution using calcined brick powder (CBP) were carried out under various experimental conditions. The uptake of chromium and nickel ions on CBP was studied at different pH values, adsorbent dosages, contact time and initial metal ion concentration. The maximum efficiency of 81.00% was achieved at pH 2.0 for Cr (VI) and at pH 4.0 the removal efficiency was 75.40% for Ni (II) at equilibrium conditions. Adsorption capacity of CBP exhibits good adsorption characteristics. The isotherms were in conformity with both Langmuir and freundlich isotherms and the constants are also evaluated.
