Abstract
A trial test procedure has been devised for testing the properties of surfactants to be used as additives to reduce nickel aerosol concentrations in the air of the working site in nickel electro-refining. More than 50 various surfactants from Russian and foreign manufacturers have been tested. Good aerosol suppression is demonstrated by "Chromin" (potassium ethylcyclohexaneperfluorosulphonate), "Progress" (secondary sodium alkylsulphate), and "Sulphonole" (sodium alkylbenzosulphonate) surfactants, which do not cause deterioration of cathodic nickel.
