“…The virial and the Frumkin models were used for the quantitative analysis of the adsorption data. Similar studies have been carried out [184] with thiourea instead of p-toluidine. The author determined, from the experimental data, the parameters of the Frumkin and the virial isotherms.…”

“…Therefore, the strong inhibition in the Zn OPD region can be better related to polymer-electrode interactions. [21][22][23] Potential-dependent PEG adsorption, through the lone pair of electrons of the oxygen atoms in the oxyethylene units, could explain the observed polarization effect. It can be assumed that the additive further controls the growth rate by blocking surface processes.…”

The effect of poly(ethylene glycol) (PEG) with molecular mass 400 (PEG 400) on the hydrogen evolution reaction (HER) and on the Zn reaction in a Na2SO4 solution and a Zn2+ -containing electrolyte was investigated by electrochemical methods. The major effect of PEG 400 on the cathode process was in the range of HER from normalH2O and bulk deposition of Zn. In the electrolyte for Zn–Cr alloy deposition, the polarization effect of PEG 400 is not sufficiently strong in the potential range of Cr codeposition with Zn, as a result of which the average amount of Cr incorporated in the coatings is relatively low, up to 6 mass %. Based on X-ray photoelectron spectroscopy and X-ray diffraction analysis, it is assumed that Cr is present as metallic Cr in the coatings under the surface hydroxide oxides. Major constituents of the Zn–Cr coatings are two hexagonal phases: η-(Zn,Cr) and δ-Zn,Cr). Also considering experiments under the industrial conditions of high electrolyte flow and high current density, it is concluded that PEG 400 is not a suitable additive for the electrodeposition of Zn–Cr alloy coatings.

A multistep reduction of Bi III ions at the dropping mercury electrode in 1M HClO 4 with the addition of methionine was examined using an impedance method in wide potential and frequency ranges. It was found that the standard rate constants and the rate constants of the first electron transfer increase with the concentration increase of methionine. The rectilinear relation k f ¼ f(G) indicates formation of Bi-methionine bridges which facilitate the transfer of electrons across the inner layer.
