“…We have reported that in the presence of this extract an inhibition efficiency is very low around 26 % at concentration of 1.00 g L -1 . [17] The degree of surface coverage values (θ) obtained from CV measurements using the Eq. (2) assuming a direct relationship between surface coverage and inhibition efficiency was tested graphically.…”

“…These oxides in contact with water in the atmosphere cause a formation of an acid rain (sulphuric and nitric acids) and promote the corrosion. [13][14][15][16][17] A rainfall with pH < 5.6 is considered the acid rain. The importance of the protection against corrosion in acidic solutions is increased by the fact that iron and steel are more susceptible to be attacked in aggressive media.…”

“…These groups adsorb on active metal surfaces and on that way they reduce the corrosion attack. [17][18][19][20][21][22] The anticorrosion activity of leaves extracts as Achillea Millefolium L., [17] Mimosa tannin, [18,19] Satureja I montana L., [19] Olea europaea L., [21] and Helichrysum italicum [22] was investigated.…”

The aqueous extract of the Helichrysum italicum leaves (HI) is tested as a corrosion inhibitor of an iron in a simulated acid rain using potentiodynamic polarisation, cyclic voltammetry and electrochemical impedance spectroscopy. Results of all electrochemical methods indicate an increase of a corrosion inhibition efficiency of the iron with the HI extract concentration. Maximum inhibition efficiency (~ 50 %) is obtained at 2.0 g L–1 HI extract. The inhibitive action is assumed to occur via an adsorption of the HI extract on the iron surface. Results indicate that the adsorption process is spontaneous and follows the Freundlich adsorption isotherm. According to the calculated ΔG value (~ 15 kJ mol–1), the corrosion inhibition of the iron occurs predominantly via a physisorption of the HI extract. The concentration of iron ions released into a solution, measured by atomic absorption spectrometry, is in accordance with the electrochemical results.

“…AR has been a serious global problem for several decades in many regions, and the response of various ecosystems to AR stress and the profound negative effects have been studied [16,78,79]. Recently, many studies have focused on the metallic material electrochemical behavior (including corrosion behavior) [82][83][84][85], reinforced-concrete structure seismic behavior and performance [86], composites wear behavior [87,88], and element leaching behavior in metal-contaminated soil [89] under AR stress. Phosphorus-related research has also become attractive to researchers.…”

With the continuation of industrialization and urbanization, acid rain (AR) has aroused extensive concern because of its potential negative effects on ecosystems. However, analysis of the current status and development trends in AR research area has seldom been systematically studied. Therefore, we motivated to conduct a bibliometric analysis of AR publications (1900–2018) using HistCite and CiteSpace software programs. Compared to traditional reviews by experts, this study offers an alternative method to quantitatively analyze and visualize the development of AR field at a large time scale. The results indicated that the overall concern of AR research studies had increased from 1900 to 2018. The most productive country was the United States, while the institution with the most publications was Chinese Academy of Sciences. “Environmental Sciences” was the most popular subject category, Water, Air, and Soil Pollution was the dominant journal, and C.T. Driscoll was the most prominent author in AR field. There were three hotspots in the field of AR, including analyzing AR status and its control policies in Europe, the United States, and China in the past few decades, investigating the ecological consequences of AR on plant histological, physiological, and biochemical traits, as well as surface water and soil properties, and the model application for quantitatively assessing AR and its effects on terrestrial and aquatic ecosystems at regional scale. Further, “behavior”, “phosphorus”, “fractionation”, “soil acidification”, “corrosion”, “performance”, “recovery”, “rainwater”, “trace element”, and “surface water” have been emerging active topics in recent years. This study can help new researchers to find out the most relevant subject categories, countries, institutions, journals, authors, and articles, and identify research trends and frontiers in the field of AR.

“…The possibility of corrosion inhibition of iron by natural antioxidants from Satureja montana L. was the focus of this study. In our earlier paper [18] the extract of the Achillea millefolium L. was investigated as corrosion inhibitor on a iron sample in an acid rain solution. The aim of the present work is to study the influence of Satureja montana L. extract on the corrosion behaviour of iron in NaCl solution.…”

The anti-corrosion behaviour of Satureja montana L. extract on iron in NaCl solution

The effect of Satureja montana L. extract (SM) and phenolic fraction of Satureja montana L. (PF) on the corrosion behaviour of iron in 0.1 mol L-1 sodium chloride solution was studied by electrochemical techniques, UV/Vis spectrophotometry and atomic absorption spectrometry. The results of all techniques showed that SM and PF contributed to iron corrosion inhibition. The calculated inhibition efficiency values were about 45% for SM and 55% for PF. Results indicate that the inhibitive action occurs via a precipitation of the Fe-complex onto the iron surface which resulting in a decrease of the passive current density. The atomic absorption spectrometry (AAS) method was applied to the quantitative determination of iron in solution. The obtained results demonstrated good agreement with results obtained by electrochemical techniques.
