Removal of Cu & Zn from industrial wastewater by using steel industry waste ( Slag ) as an adsorbent

Department of Applied Sciences & Humanities, Moradabad Institute of Technology, Ram Ganga Vihar Phase – 2, Moradabad-244001 Abstract The removal of two heavy metals Cu and Zn from their aqueous solution, using steel industry slag as an adsorbent was studied as slag consist of calcium oxide, aluminum oxide, magnesium oxide etc. The research is a bench scale experimental type and analysis have performed by using different amount of adsorbent in solution with five different concentration of both metals and also in mixed combination. About 93.6% and 100% Cu removal was achieved by using 1 and 3g adsorbent for solution having concentration of 5 and 10 mg/L Cu. It was also found that adsorption efficiency depend on the amount of adsorbent as adsorption efficiency of Zn was increased from 82% to 100% in the same solution(5 mg/L).It was also observed that adsorption efficiency was decreased about 2% and 4% of Cu and Zn in Mixed metal solution.
