Adsorption and electrochemical studies on surfactant modified cellulose acetate membranes

Colloid Journal (Impact Factor: 0.79). 02/2008; 70(1):101-104. DOI: 10.1134/S1061933X08010158


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
