The effect of the mixed adsorption layers: tetramethylthiourea and chosen detergent on the Zn2+ ions electroreduction is described. The detergents concentration was 7.5·10-4 M, which was lower of its critical micellation point. Three detergents: cationic, neutral and anionic were chosen for this study. First two detergents inhibited the Zn2+ ions reduction at mercury electrode, the last detergent accelerated this process. Tetramethylthiourea eliminated the inhibiting effect of the detergent and accelerated the studied process stronger than in the detergents absence. Standard rate constants of Zn2+ ions electroreduction were determined by cyclic voltammetry and impedance measurements
