Abstract
The surface activity of certain bicyclic surfactants from the camphane group of terpene series in aqueous and saline solutions was studied. It has been shown that bicyclic compounds with a rigid hydrocarbon framework exhibit high surface activity, especially in electrolyte solutions. This fact makes it possible to use them in the flotation of soluble salts. The main characteristics of the adsorption layer were determined: surface activity, saturation concentration of the adsorption layer, maximum adsorption, and the area occupied by a molecule in the adsorption layer. It is shown that the structure of the hydrophobic radical has a significant effect on the structure of the surface layer, and the presence of an aliphatic chain in the hydrocarbon skeleton contributes to an increase in the surface activity of the surfactant.
