摘要
Concentration dependence of the surface tension was studied in the vicinity of compositions of four solutions of the mutual system H2O:Na+, H+, Zn2+ parallel to NO3-, DS- (DS is dodecyl sulfate). Adsorptions of ions on the solution-vapor interface were calculated. Zinc cations were removed to the maximum permissible concentration from aqueous solutions by froth separation.
