Removal of Cu, Ni and Zn from Wastewaters by the Ferrite Process

摘要: Applicability of the ferrite process in industrial wastewater treatment was investigated this study. Preliminary experiments were carried out on synthetic samples, bearing copper, nickel, and zinc cations, to determine optimum experimental conditions providing formation satisfactory metal removal rates from solutions. These then applied copper industry with same heavy higher concentrations. Experiments resulted about 100 % both zinc, 99.0 nickel at pH 11, 50°C, 1000 ml min−1 aeration, 2 hours oxidation, ratios Cu2+:Fe2+=1:4, Ni2+:Fe2+=1:9; Zn2+:Fe2+=1:10 for particular wastewater. As well as pH, contact time Fe2+ concentration solution also significant affecting hence efficiencies metals. Providing that are satisfied, can successfully be remove met...
