Summary:We study apricot pomace extract as a novel ecologically friendly inhibitor of the corrosion of steel in neutral aqueous solutions. It is shown that the efficiency of corrosion protection of steel with the help of apricot pomace extract in a 0.5 M NaCl solution increases with its concentration and the duration of holding. The data of gravimetric and electrochemical measurements demonstrate that a film is gradually formed on the steel surface with time (~ 48 h) and its thickness exceeds 800 nm. The morphology of the protective film is studied by the methods of scanning-electron microscopy and atomic-force microscopy. The chemical composition of the protective film is investigated by the method of FT-IR spectroscopy.
