Abstract

This work is devoted to the electroflotation purification of wastewater from copper and nickel ions in the presence of surface-active compounds (SACs) and oil. The kinetics of these processes were studied. It was shown that the presence of oil decelerates the initial stage of the process of extraction of nickel(II) and copper(II) hydroxides. SACs do not affect the extraction of copper hydroxide and the process is intensified for nickel hydroxide. The possibility of extracting metal ions as phosphates was demonstrated.
