“…However, organic surfactants have found wide use due to their specific properties as the main components of detergents, in electroplating, in degreasing solutions, and in paint and paper industry; they are often found in wastewater [5,6]. Electroflota tion is often used for purification of wastewater in electroplating industry [7] from nonferrous metals [8], including chromium compounds [9,10] in Russia and abroad [11,12].…”

The effect of various surfactants on the physicochemical parameters (particle size and zeta poten tial) of the disperse phase of copper, nickel, and zinc hydroxides at concentrations of cationic, anionic, and nonionic surfactants of 2, 10, 50, and 100 mg/L at pH of 9.5-10.5 was studied. The efficiency of their elec troflotation extraction into a flotation froth was determined in a laboratory electroflotation module with anti wear oxide electrodes with efficiency of higher than 95% (initial concentration 50 mg/L, in the form of flo tation sludge, processing time no more than 30 min, current density 0.2 A/L).
