Sažetak
The mixed adsorption layers of tetramethylthiourea and a cationic detergent formed at electrode
surface in NaClO4 (1 mol dm–3) are described. The systems were characterized by the measurement of differential
capacity, zero charge potential, and surface tension at this potential. The data were analyzed to
obtain the surface pressure and relative surface excess of tetramethylthoiurea as a function of electrode
charge at bulk concentration of studied compounds. It was stated that the adsorbing tetramethylthoiurea
molecule pushed out the water molecule instead of the detergent molecule from the electrode surface.
The constants of the Frumkin and corrected Flory-Huggins isotherm point to a decreased TMTU adsorption
energy in the cationic detergents presence and stronger repulsive interaction. Electrostatic parameters
of the inner layer were assigned. In the range of more negative potentials, mixed adsorption
layers were described by investigating the kinetics of the Zn2+ ions electroreduction as a piloting ion.
