Inhibitory effect of extracts from three date varieties namely khalt (kha), Lassiane (La) and Tadmamt (Td)), and the mixture of date varieties as environmentally friendly corrosion inhibitor for carbon steel in 1M HCl is studied by means of electrochemical tests such as electrochemical impedance spectroscopy (EIS), and Tafel polarization. It's been obtained that in 1.0 M HCl solution the date e...
