Technology for the Purification of Electroplating Washwater from Cadmium Ions by Membrane and Membraneless Electrolysis

A technology for removing toxic Cd 2+ from electroplating process electrolytes and washwater containing or Cl – is proposed. This technology makes it possible to decrease the concentration of Cd 2+ in treated solutions to 0.1–0.07 g/L and the Cd 2+ ingress into plant waste waters by 288–366 times an...
