This study describes the ability of Calicotome extract (CE) to inhibit the corrosion of C-steel in polluted NaCl (3.5%NaCl+ 16 ppm Na2S) solution which carried out using chemical (weight loss, WL)and electrochemical(potentiodynamic polarization, PP, electrochemical impedance spectroscopy, EIS and electrochemical frequency modulation, EFM)techniques. Temkin isotherm was tested to describe the adsor...
