Abstract The aim of this paper is to investigate peach pomace extract as a cheap, raw, green and non-toxic anti-corrosion material for mild steel corrosion in neutral media of 0.5 M NaCl solution. The chemical profile of the extract was analyzed using gas chromatography mass spectrometry (GC–MS) and high performance liquid chromatography analysis. Gravimetric, PR technique, scanning electron microscopy were used to study the corrosion inhibitive. The influence of immersion period on inhibition efficiency was evaluated. The mechanism of action of the inhibitor is also discussed. The gravimetric, polarization measurements and surface analysis evinced that the growth of inhibitory properties is prolonged and corrosion rate reduction after 40–50 h of exposure. The potentiodynamic polarization curves indicated that PPE acts as a mixed-type inhibitor. The phenomenon of prolonged action “40–50 h” and the influence of the time of film formation on its effectiveness were explained. The formation of polymerisation flavanol-aldehyde adduct, polymers of flavan-3-ols-anthocyanins and oxidation compounds of the p-quinones structure due to extract transformation in water causes main corrosion reduction in 40–50 h.

1 Introduction Corrosion protections of metals are part of the environment protection, which occupies nowadays a key place in the chemical engendering. various methods are known to improve the corrosion resistance of metals and alloys. The most effective is the modification of the surface of metals as well as the use of corrosion inhibitors [1–6]. If there is a need for anti-corrosion protection of metals operating in aqueous media containing chlorides, it is promising to use corrosion inhibitors. Most of the traditional organic and inorganic inhibitors are synthetic compounds, which are costly and often lead to serious environmental problems. Inhibitors based on "green" organic compounds have been used widely to prevent corrosion of mild steel in water systems that was induced chlorides. * Victoria Vorobyova [email protected] 1

Integrated valorisation of fruit waste is a progressive direction of resource conservation, owing to their environmental and economic values. A significant amount of waste is generated in the processing of fruit and berry crops. Peach pomace is a waste produced by the fruit processing industry in massive quantities each year (21.6 million tons in 2018) which may reach from 15 to 28% of transformed raw material, depending on the process conditions [7].
