“…Mahdavian et al have studied the effect of ligand size of Zn complexes on the corrosion inhibition of mild steel [ 13 ], same researchers also reported the corrosion protection performance of different transition metals complexes of acetylacetonate [ 14 ]. Sayed et al used ethylenediamine as ligand [ 15 ] for some transition metal complexes and studied for protection of copper. The correlation between corrosion inhibition activity of the ligands and their Co(III) complexes have been discussed by Khaled and coworkers [4] on the basis of electrochemical methods and molecular modeling data.…”

“…The corrosion rate of copper decreased in the following order: En ӷ Cu complex ӷ Cd complex Ͼ Zn complex Ͼ Ni complex. 16 Survila et al 17,18 recently analyzed thermodynamic and kinetic aspects of Cu 2 O formation in ethylenediamine. Their work indicates that copper solubility ex-pands over a wider pH range in the presence of ethylenediamine.…”

Potential-pH equilibria and potentiodynamic polarization studies were used to examine the electrochemical behavior of copper in aqueous ethylenediamine solutions. Potential-pH diagrams for the copper-water-ethylenediamine system were derived at different total copper false{CuTfalse} and ethylenediamine false{EnTfalse} activities. The diagrams show that the solubility range of copper is significantly extended in the presence of ethylenediamine. Polarization experiments were conducted in deaerated and aerated aqueous solutions of 10−2M ethylenediamine with 10−3M cupric sulfate, and 10−4M ethylenediamine with 10−5M cupric sulfate over a wide pH range. The results of these experiments are discussed in terms of relevant potential-pH diagrams. Good correlations were observed. © 2002 The Electrochemical Society. All rights reserved.

“…The study of corrosion and corrosion inhibitors for this metal is also investigated [1][2][3][4][5][6][7][8]. There is a general agreement in the literature that the anodic layers, on the copper surface, presents a simple (Cu 2 O) or a duplex (Cu 2 O/CuO, Cu(OH) 2 ) structure, and depend on both the electrode potential and the presence of buffering ions (basic or acids), which have different effects on the anodic reaction of copper, such ions participating in the reactions involving the dissolution of the metal and the passive film formation [6,9].…”
