Abstract

The electrochemical properties of an interface between two immiscible solutions of electrolytes are investigated as the interface is altered by adsorption of the water soluble protein bovine serum albumin. Cyclic voltammetry and electrical impedance spectrum analysis are employed as the tools of this study. The impedance behavior in the presence of bovine serum albumin shows that the protein macromolecule is adsorbed at the interface. The imaginary impedance of the interface increases with increasing concentration of bovine serum albumin to about 10 ppm, suggesting that the adsorbed monolayer forms gradually, which causes the interfacial capacitance to decrease. The impedance behavior has been analyzed as a function of applied interfacial potential. The potential of zero charge of the interface was obtained for different concentrations of bovine serum albumin. The impedance behavior is further discussed as a function of pH and temperature.
