Electrolytic copper refining allows one to obtain high-purity copper, so analyzing the main ways impurities transition into electrolysis products is a rele

The effect of benzotriazole (BTA) and sodium ethylenediamine tetraacetate (EDTA) to the magnesium dissolution intensity under external anodic polarization was studied. The inhibiting properties of BTA and EDTA in electrochemical corrosion of magnesium were found in the concentration range from 0.005 to 0.0125 M in sodium sulfate solution and from 0.0025 to 0.03 M in sodium chloride solution. In the presence of inhibitors, magnesium dissolution becomes uniform with decreasing surface hydrogenation and crumbling intensity of small particles into solution.

A method for determining the Faraday current efficiency (CeF) based on the ratio of partial winning currents of metal and hydrogen is considered. To calcul
