The effect of addition of cosmetic argan oil (CAO) on the corrosion of
copper in 2 M H3PO4 and NaCl 0.3 M has been studied by weight loss measurements,
potentiodynamic polarisation and Electrochemical Impedance Spectroscopy (EIS)
measurements. The inhibition efficiency was found to increase with inhibitor content to
attain 98% for CAO at 7g/L. Inhibition efficiency E (%) obtained from the various
methods is in good agreement. The temperature effect on the corrosion behaviour of
copper in (2 M H3PO4+ 0.3 M NaCl) was studied by potentiodynamic technique in the
range from 298 to 323 K. The associated activation energy has been determined.
