The influence of surfactant on cellulose acetate/chitosan membrane has been investigated. A basicapproach to cellulose acetate/chitosan membrane is also mentioned. Nonionic surfactants are disruptedthe normal permeability of the characteristic membrane. Electrochemical characterization such asconductance, flow, flux and permeability are measured in various concentrations of the electrolyteand surfactants. Membrane potential is determined by the combination of the properties of ions of theelectrolyte, surfactant and membrane. The synthesized membrane was found to be cation selectivewith measured membrane potential found to be negative in all cases. The value of membrane potentialwas varying in different concentration of the electrolyte and surfactant. The Teorell Meyer and Sievers(TMS) theoretical method was employed for calculating the Transport number, perm selectivity andfixed charge density of the membrane by using the data of membrane potential across normal andsurfactant modified membrane with electrolytic solution of NaCl. The variation of fixed density andperm selectivity also depends on the concentration of the electrolyte and surfactant (Tween 20 andTween 60).
