Аннотация: he mutual influence of different functional organic additives in sulfate electrolyte of copper plating during co-adsorption on the surface of copper cathode was investigated by ellipsometric method. The tendency to adsorption on copper increases in the series: bis-(sodium sulfopropyl) disulfide (SPS) < 4,4′-dibenzene disulfonic acid disulfide disodium salt (Avangard) < bis(2-amino-phenyl)disulfide (APhDS). This can be explained by the transition from an aliphatic to an aromatic structure, as well as the presence of two amino groups, which may contribute to the increased stability of the chemisorption complexes. The adsorption-desorption behavior of polyethylene glycol studied as an inhibitor is practically independent of the molecular weight, but PEG-8000 with high molecular weight promotes more pronounced adsorption in the blends. Among the levelers, Janus green is more adsorption efficient towards copper compared to aminobenzothiazole due to the presence of several aromatic and heterocyclic rings as well as nitrogen-containing functional groups in its structure. As a result, the highest adsorption capacity is shown by mixtures containing APhDS and Janus green, for which the maximum change in the ellipsometric phase angle is observed if PEG-8000 is additionally present.
