Application of Iron Nanoparticles for Industrial Wastewater Treatment
Sukopová, M. ; Matysíková, J. ; Škvoran, O. ; Holba, Marek
Our study evaluated copper and nickel removal from metal finishing industry by using of nZVI. Lab-scale tests were performed with processing wastewater. Concentration of metals in raw wastewater was 22.4 mg/L for copper and 1.3 mg/L for nickel. 99 % of copper was removed by nZVI dose 3 g/L in 73 hours, likewise the highest removal efficiency of nickel was up to 80 % for the same nZVI dose in 6 hours. The removal efficiency 80 % for nickel was sufficient. The reaction seems to be relatively fast, high removal efficiencies were observed after 30 minutes. Further time of exposure was beneficial only for copper removal, nickel concentration become stable after 2 hours. Reaction conditions were monitored only but no effect of pH, temperature or conductivity was investigated. The results showed possibility to remove heavy metals from industrial wastewater in environmentally friendly way. Further research with real wastewater is necessary to get more reliable results.
