LAHMADY, Sara et al. Investigation of Ziziphus Lotus Leaves Extract Corrosion Inhibitory Impact on Carbon Steel in a Molar Hydrochloric Acid Solution. Port. Electrochim. Acta [online]. 2023, vol.41, n.2, pp.135-149. Epub 30-Abr-2023. ISSN 0872-1904. https://doi.org/10.4152/pea.2023410203.
In this research, ZL leaves extract was used as a new friendly inhibitor for improving CS corrosion resistance in a 1.0 M HCl solution. The extract performance was evaluated by PDP and EIS techniques. The outcomes of this investigation showed that corrosion IE% of ZL leaves C2H5OH extract raised from 86 to 95%, with concentrations from 1 to 3 g/L. EIS method confirmed that the extract IE% was stable in the long-term. However, when the test temperature increased from 293 K to 323 K, IE% decreased from 95 to 90%. PDP experiments results revealed that ZL leaves extract operated as a mixed-type inhibitor, with anodic predominance.
