In this paper the analytical method used for separation and identification of the corrosion products of copper specimens corroded by sulfide polluted sea water has been described. Many solvents were used: methanol, to remove sodium, magnesium and copper chlorides; glycine, to dissolve the bivalent compounds of copper not bonded to sulfide; NH4Cl, to dissolve Cu2O; KCN to dissolve the copper sulfides. The samples corroded in sea water showed the formation of oxychlorides and carbonates and CuS, Cu2S, Cu2O. These results are partially confirmed by X-ray diffractometric analysis, which showed only the formation of CuS, Cu2S, and Cu2O.
