摘要：
Methods of precision tensiometry and two-phase titration were used to determine thermodynamic parameters of the Gibbs adsorption of ionogenic surfactants at solution/air and solution/cellulose acetate membrane interfaces. It was shown that the adsorption equilibrium constant and the limiting monolayer capacity of the surfactants studied depend significantly on the ionic strength and pH of the solution. The role of electrostatic and specific effects on the adsorption capacity of ionic surfactants is examined.
