Inhibitive effect of Artemisia Judaica Herbs extract on the corrosion of carbon steel in hydrochloric acid solutions

Abstract

Artemisia Judaica herb extract (AJH) was tested as an eco-friendly corrosion protection of carbon steel (CS) in 1.0 M hydrochloric acid as attacking medium utilizing non electrochemical methods (mass reduction (MR)), and electrochemical methods such as (EIS) AC electrochemical impedance spectroscopy, and (PP) Tafel polarization tests. The obtained data revealed that the protective efficiency increased with increasing extract dose and also increased with increasing temperature. Surface examination was performed by (AFM) atomic force microscope (in order to determine the degree of roughness of the CS surface), (SEM) scanning electron microscope (in order to determine the film formed on CS surface) and (FT-IR) Fourier transforms infrared spectroscopy (in order to determine the adsorbed groups on CS surface). These tests revealed that the extract molecules form a film on CS surface. The AJH extract was adsorbed physically and spontaneously on CS surface and follows Langmuir's isotherm. The adsorption (K ads ,

Relationship between the inhibition and antioxidant properties of the plant and biomass wastes extracts – A Review

“…The increase of publication shows an exponential trend. Just in the past 2018, numerous naturally occurring products such as Nettle leaves [26], Red Algae Halopitys Incurvus [27], Prosopis juliflora [28], Barley Agro-Industrial Waste [29], Matricaria recutita chamomile [30], Rollinia occidentalis [31], Glycyrrhiza glabra leaves [32], Holoptele integrifolia leaf [33], Ginkgo leaf [34], Centaurea cyanus [35], Crataegus oxyacantha and Prunus avium plant [36], Pongamia Pinnata [37], Sida Cordifolia [38], Allium sativum (garlic extract) [39], Raphanus Sativus L. [40], Borago officinalis L. [41], Cuscuta reflexa [42], Mature areca nut husk [43], Pisum sativum peels [44], grape pomace [45][46][47], Artemisia Judaica Herbs [48], and Opuntia Ficus-Indica [49] have been evaluated as potential corrosion inhibitors. The increase in interest in green inhibitors has stroked the eager of many researchers round the globe to search for natural plant based inhibitors.…”

A combined experimental and theoretical study of (E)-ethyl 3-(4-methoxyphenyl)acrylate as corrosion inhibitor of iron in 1 M HCl solutions

“…Attempts to find eco-friendly, inexpensive and efficient corrosion inhibitors are still intensively underway. A potential candidate as a corrosion inhibitor is natural product compounds [2][3][4][5][6]. Natural product compounds generally utilize their heteroatom groups (O, N, and P) and their π electron to interact with metal for inhibiting corrosion processes [7].…”
