Essential Oil of Aaronsohnia Pubescens Subsp. Pubescens as Novel Eco-Friendly Inhibitor for Mild Steel in 1.0 M HCl %K Corrosion inhibition %K Electrochemical methods %K Aaronsohnia pubescens subsp. pubescens %K essential oil %R %X The essential oil from the aerial parts of Aaronsohnia pubescens subsp. pubescens plant (APS oil) was extracted by hydrodistillation, and then its composition was analyzed by gas chromatography (GC) and GC-mass spectrometry (GC/MS). We identified thirty-four constituents presenting 87% of the total amount, Which, Carvacrol (13.9%), α-Pinene (10.3 %), E-Anethole (10.1%) and Ar-Turmerone (9.3%) were identified as major constituents of APS oil. The corrosion inhibition and adsorption (CIA) performance of the APS oil on the corrosion mild steel (MS) in 1M hydrochloric acid was evaluated by the weight loss (WL) analysis and electrochemical assays. The weight loss outcomes indicate that APS oil shows a worthy inhibitory efficiency of 89.88 % which reached at 3g.L-1 and 343 K. The charge transfer process mainly controls the results of EIS measurements, PDP measurements showed that the studied APS oil performs as a mixed-type inhibitor. Furthermore, the adsorption on the MS surface follows the Langmuir model. %U https://www.abechem.com/article_43206_25168098d11a2d35e2dbcb7c9d6ed9d0.pdf
