Abstract

Niaouli Essential Oil (NEO) was analyzed by GC and GC/MS and its mainly compound is the Eucalyptol (60.01). The corrosion inhibitionof Niaouli Essential Oil (NEO) fortinplate has been studied in 3 NaCl at pH = 2 by Tafel polarization and electrochemical impedance spectroscopy (EIS) techniques. The results showed that the inhibition efficiency of NEO increaseswith concentration and decreases with temperature. It was found that NEO behavesas cathodic inhibitor at the concencetration rage 0.1-0.4 g L-1 and a mixed type inhibitor at 0.5 g L-1. EIS showed that the inhibitor addition decreases the double-layer capacitance and increases the polarization resistance. The adsorption process of NEO obeyed the Langmuirisotherm. © 2017, University of Mohammed Premier Oujda Morocco.
