Effect of electrolyte on adsorption of polyallyl amine hydrochloride/sodium dodecyl sulphate at water/tetradecane interface

- Adsorption from mixed PAH/SDS solutions is studied at water/tetradecane interface.
- Thermodynamic model for the competitive adsorption of complex formation is proposed.
- At low SDS concentrations adsorbed layer is determined by adsorption of complexes.
- At high SDS concentrations effect of the PAH + SDS complexes is negligibly small.
- The agreement between experiment and theory confirms the proposed physical picture.
