Corrosion of copper and its inhibition have been studied by polarization measurements and in situ atomic force microscopy. Electrochemical measurements proved that all examined inhibitors hindered the corrosion of copper in sulphate containing acidic solutions. These chemicals are cathodic type inhibitors having influence on reduction of dissolved oxygen. The inhibition efficiency decreased in the following order: 5-IPBDT > 5-BDT > 5-MBDT > 5-TDT. Results of atomic force microscopy showed that all inhibitors formed a very thin (mono-)layer on the surface of copper. In blank solution the corrosion product formed a rough surface.
