    Abstract

    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.
