چکیده مقاله
The corrosion inhibition effect ofCalligonum comosum(CC) extract on copper (Cu) in
2 mol L
1
HCl medium has been investigated by potentiodynamic polarization and electrochemical impedance spectroscopy methods. The polarization studies showed that CC extract
acts as mixed type protection and maximum inhibition efficiency. 80.06 pct in 2 mol L
1
HCl is
obtained at 0.8 g L
1
CC extract. The Nyquist plots showed an increase of the charge-transfer
resistance with increasing of the inhibitor concentration and decrease double-layer capacitance.
The inhibitory action of the extract was discussed in view of the Langmuir adsorption isotherm.
