Tests of new surfactants for emission decrease of hydro-aerosols of nickel salts have been carried out. The optimum concentration about 5 mg/dm³ has been chosen by results of the spent laboratory researches. At such concentrate of "Aviton" reagent in electrolit the following is observed: low foaming; cathode current output about 98,5%; emission decrease of hydroaerosols of nickel in a working zone; the specific energy consumption on ton of cathodic nickel about 1778,3 kWh/t.
