The kinetics of the electrodeposition of zinc to the steel base of the sulfate electrolyte supplements with synthetic surfactants was studied. Found that at potentials more positive than the equilibrium value the process of pre phase zinc deposition. Additives synthesized organic compounds adsorbed to the surface of the electrode at its cathodic polarization, increasing of overvoltage process. The adsorption is in the range of 0,5•10-7 to 2,6•10-5 mol/сm2.
