“…1a). Several scientists in their studies (Table 3) reported similar results [2,4,6,[15][16][17][18][19], which confirm that the SSE act as effective inhibitors. The evolution in inhibition efficiency may be attributed to the adsorption of the particles at the carbon steel (X52) surfaces [20].…”

The inhibitory effect of the crude ethyl acetate extract of Saccocalyx satureioides was estimated on the corrosion of carbon steel (X52) in 1 M HCl solution sing weight loss measurement, potentiodynamic polarization, electrochemical impedance spectroscopy and scanning electron microscopy techniques. Potentiodynamic polarization curves indicated that the plants extract behaves as a mixed-type inhibitor. The adsorption of the inhibitor on the carbon steel surface was found to follow Freundlich adsorption isotherm. The free energies, enthalpies and entropies for the adsorption and dissolution process were discussed in details. The inhibiting action increases with increasing concentration of the extract. The results obtained show that the extract of the aerial parts of Saccocalyx satureioides could serve as an effective corrosion inhibitor of carbon steel (X52) in hydrochloric acid medium.

“…The use of inhibitors is one of the most proficient methods for protection of metals from corrosion in acid medium. Organic compounds containing N, O, S heteroatoms and p electrons in their molecules are considered as effective corrosion inhibitors [2][3][4][5]. The inhibitor molecules form a protective film on metal surface that prevents corrosion [7].…”

Expired atorvastatin drug as corrosion inhibitor for mild steel in hydrochloric acid solution

The application of expired drugs as corrosion inhibitors provides a cost effective and environmentally benign alternative to otherwise tedious and costly disposal/ degradation process. In this context, we herein investigate the use of expired atorvastatin (EA) for corrosion inhibition of mild steel in 1 M HCl solution using weight loss, electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization (Tafel) methods. Fresh atorvastatin (FA) drug was also used for above studies for comparison purpose to understand whether there is any significant difference between the inhibition efficiency of the two after the expiration date of the drug. EIS analysis shows an increase in polarization resistance due to the adsorbed inhibitor molecules on metal surface. Potentiodynamic polarization indicates that both the EA and FA act as mixed-type inhibitors but predominantly behave as cathodic inhibitors. The adsorption of EA and FA on mild steel surface follows the Langmuir adsorption isotherm. SEM shows a smoother surface of mild steel in the presence of FA and EA drug in acidic solution. Both the fresh drug and its expired counterpart showed almost similar results in all the studies, thereby verifying the validity of the expired atorvastatin drug as a novel and efficient corrosion inhibitor for mild steel.

“…Natural products, which are available in nature and can be extended, were a good alternative for corrosion inhibitor. Several studies have developed a corrosion inhibitor material, which is derived from natural plants such as Guava [11], Ananas sativum [12], Azadirachta indica [13], Henna [14], Apricot [15] Green Tea [16], Pluchea Indica L [17], and Geissospermum laeve [18]. The protection mechanism of organic inhibitors is mostly based on the absorption of ions or molecules into the surface of steel.…”

Abstract. The effect and mechanism of green corrosion inhibitor of Morinda Citrifolia (Noni) toward low carbon steel material has been researched. The general background is to develop the cheap and eco-friendly corrosion inhibitor based on components taken from tropical plants that grow +in Indonesia. This research aims to determine the effectiveness of the use of the extracts of noni as green corrosion inhibitor of carbon steel material in aggressive environment. The medium applied for this experiment is 3.5% natrium chloride solution. The variation of the concentration and immersion time duration has been applied as the experimental parameters. All the work was done at room temperature. The corrosion rate was measured by electrochemical polarization method with CMS 600-Gamry instruments and weight loss. The adsorption of inhibitor into the metal surface, which induced bonding formation after immersion was observed by using FTIR method. Inhibition mechanism was observed by polarization curves and fitted by the Langmuir adsorption models. The experimental results show that the higher concentration of inhibitor increasing the inhibition effect. The optimum inhibition is obtained at 3 ppm noni fruit extract, after immersion for about 288 hours. The corrosion rates obtained was 1.385 mpy, with the inhibitor efficiency of 76.92%. The monolayer film is formed coating the surface material as a result of mixed type corrosion inhibitor behavior of Noni. It can be concluded that this green inhibitor is effective to be used for low carbon steel material.
