Abstract

The minimal expenditure of anionic surfactant, sodium dodecyl sulfate, required for decreasing concentrations of nickel and copper ions to the maximum permissible concentration was determined experimentally. A possibility of selective recovery of nickel ions by foam separation with sodium dodecyl sulfate under conditions of complex formation of copper cations with thiosulfate anions was studied.
