Copper recovery from industrial wastewater - Synergistic electrodeposition onto nanocarbon materials

In this study, copper present in industrial waste water with a variety of other impurities (Fe, Mg, Al, Zn, As) was subjected for selective electrochemical recovery. The recovery conducted directly on carbon nanostructures order to create added-value products synergistically. In-depth and structural analysis showed that single/multi-walled nanotubes (CNTs) graphene composites could provide an excellent substrate Cu's Furthermore, formulations based them also enabled the formation even Cu deposits surface from wastewater solutions without further bath condition adjustments. After just 1-h electrodeposition at ?0.1V vs. SCE, nanocomposite CNTs obtained. recovered exclusively accounted 45% total weight composite.
