SYNERGISTIC CORROSION INHIBITION ACTIVITY OF THE CHICORIUMINTYBUS EXTRACT AND IODIDE IONS FOR MILD STEEL IN ACIDIC MEDIA

ABSTRACT Herein, An examination into the corrosion inhibition of mild steel (MS) in 1.0 M HCl by the Chicoriumintybus extract as a green inhibitor had been achieved via chemical, electrochemical and morphological measurements. The effect of KI additives on corrosion inhibition efficiency was carried...

Chicoriumintybus extract Mild steel Acid corrosion Synergistic effect Surface morphology ABSTRACT Herein, An examination into the corrosion inhibition of mild steel (MS) in 1.0 M HCl by the Chicoriumintybus extract as a green inhibitor had been achieved via chemical, electrochemical and morphological measurements. The effect of KI additives on corrosion inhibition efficiency was carried out using a weight loss method. The results reveal that the Chicoriumintybus extract inhibited the corrosion reaction by adsorption onto the metal/solution interface. Inhibition efficiency, increased with the Chicoriumintybus concentration and synergistically increased with the presence of KI. The addition of iodide ions to the Chicoriumintybus extract raises inhibition efficiency of 74 to 99%. Polarization data suggest that the Chicoriumintybus extract acts as a mixed inhibition-mechanism. This observation was further corroborated by the fit of experimental adsorption data to the Temkin isotherm. The results were confirmed by AFM, SEM images and ATR-IR for the surface morphology.info:eu-repo/semantics/openAccessSociedad Chilena de QuímicaJournal of the Chilean Chemical Society v.65 n.1 20202020-03-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0717-97072020000104672en10.4067/S0717-97072020000104672
