A review of the literature dealing with the electrochemical corrosion of copper and its alloys with purpose to find the most suitable inhibitor for its protection has been done. According to their chemical composition of corrosion inhibitors are divided into inorganic and organic inhibitors. Inhibition of alloying metals are possible (such as the addition of arsenic alloy components in brass, preventing its unzincanization). The paper reviews the theoretical basis of application of inhibitors to protect metals from corrosion as well as an overview of current research application of inhibitors to protect copper and copper alloys. Benzotriazole (BTA) is most often used corrosion inhibitor for copper and its alloys in acidic and alkaline solution, because of its high inhibition efficiency. The lowest concentration of inhibitor for protection of copper in various solutions was 0.05%, and for the protection of copper in contact with steel is 0.1%. On the surface of copper and brass BTA forms a protective Cu-BTA film. However, BTA is like many other synthesized organic inhibitors is very toxic and if used in very small concentrations. It turned out that the AETD, AETDA and PTAT good corrosion inhibitors of copper mixed type with the efficiency of inhibition increases with concentration. Due to the adverse effects on the environment, health and other bodies in recent times the focus of research is transferred to the inhibiting action of biological molecules or mixtures of natural compounds called "Green inhibitors".

“…The high efficiency of this molecule is commonly attributed to the formation of a polymeric film on copper surface [1][2][3][4][5][6][7][8][9]. Since BTA can interact also with the iron surface, this molecule also shows interesting properties even towards the corrosion inhibition of iron, e.g.…”

5-Alkyl derivatives of benzotriazole (1-12 carbon atom long alkyl chain) were tested as inhibitors of pure iron corrosion in sulphuric or hydrochloric acid at 25°C and pure copper corrosion in acidic sulphate and saline solutions at 30°C. This series of compounds was more efficient in contrasting copper than iron corrosion and, generally, the longer the alkyl chain the higher the inhibiting performances and the longer the persistency of the inhibiting action. However, due to a decrease in the solubility, the maximum inhibiting effects were produced by the hexyl derivative. In the case of iron, these compounds were more efficient in the hydrochloric acid solution than in the sulphuric one, while for copper they were more effective in the acidic sulphate solution than in the acidic chloride solution. The higher inhibiting effects for copper can be justified by the mode of BTA adsorption, that consists in chemisorption, instead of physisorption occurring on iron.

In previous studies on the mechanism of the BTAH inhibition of the copper 18,19) , the layer formed by the adsorption of BTAH or complex formation acts as a physical barrier to the inward diffusion of aggressive ions. Due to this barrier, the passive behavior is indicated in the polarization curves.…”

The corrosion inhibition effect of benzotriazole on copper and steel in simulated tap water was investigated by using potentiodynamic polarization, electrochemical impedance spectroscopy and a quantum chemistry analysis. The corrosion inhibition ef ciency for copper and steel was accordingly increased with an increasing of the benzotriazole concentrations. However, the electrochemical test showed a signi cant difference between the inhibition ef ciency of copper and steel. From molecular theory and the adsorption isotherm, the difference between the d-orbital structure of copper and steel affects the adsorption stability of benzotriazole on the metal surface. This postulation is well correlated with the results of the quantum chemical analysis.
