Rezumat: 2+ By means of potentiodynamic and galvanostatic methods the influence of H2SO4, Zn and hydroxyethylated-2-butyne-l, 4-diol (Ferasine) on the electroextraction of copper from sulphate 2+ electrolytes was studied. It was established that Zn -ions and organic additive Ferasine decreases the cathodic currents and quantities of deposited copper during scanning to different vertex potentials only in electrolytes containing sulphuric acid. Thus they inhibit the process of copper deposition. Dense and smooth copper coatings on with current efficiency higher than 95% are deposited when 2+ -3 -2 Cu concentration is higher than 5.0 g.dm and current density is in the range 0.5 ÷ 2.0 A.dm . More fine-grained coatings are obtained in the presence of H2SO4 and organic additive hydroxyethylated-2- butyne-l, 4-diol (Ferasine).
