This study investigated the effect of different concentrations of Prosopis farcta extract on the electrochemical properties andcorrosion of St37 steel in 1 M hydrochloric acid medium. The investigation showed that Prosopis farcta extract contains amixture of oily compounds, alkaloids, and flavonoids, which give it notable corrosion inhibition ability. The results of Tafelpolarization, electrochemical impedance, and weight loss tests were consistent in confirming the corrosion inhibition effectof this extract. The maximum percentage inhibition achieved in the Tafel test, EIS test, and weight loss test was 91%, 94%,and 82% respectively. Experiments showed that Prosopis farcta extract classifies as a mixed type corrosion inhibitor. Theinhibition effect of this extract is the product of the adsorption of its molecules in the electrolyte–metal interface, and thisadsorption follows Langmuir isotherm. The adsorption activation energy of Prosopis farcta extract for St37 steel in 1 Mhydrochloric acid was calculated to −10.945kJ∕mol , which shows the spontaneity of this adsorption in this system.
