description | The possibility of the modification of a cellulose acetate membrane upon adsorption of ionic surfactants, cetyl pyridinium chloride and sodium dodecyl sulphate has been investigated on the basis of membrane potential studies. For the estimation of the extent of adsorption, surface tension measurements were carried out in the presence and absence of cellulose acetate membrane using surfactant solutions of variable compositions. The results have also been used for the characterization of the thermodynamic equilibrium, which the membrane surfactant system attains upon surfactant adsorption, in terms of the immobilization constant. |
