Abstract

The corrosion behavior of cold rolled steel in different concentrations of peracetic acid (PAA) has been studied by electrochemical technique at 0 °C, 10 °C, 20 °C and 30 °C, respectively. Electrochemical parameters like corrosion potential, corrosion current density and corrosion rate were determined. The results show that concentrations of PAA and test temperatures can affect the corrosion rate obviously. The corrosion rate increases with increase of the concentration of PAA at each temperature, but the maximum corrosion rate appears at 20 °C at each same concentration of PAA. The characteristic chemical reactions were used to investigate the form of Fe ions dissolved in PAA solutions. It was found that the Fe³⁺ ions were the dominant corrosion products. A probable corrosion mechanism is presented to explain the experimental results.

Introduction

PAA is a strongly oxidizing acid, which has a long history of usage as disinfectants and sterilizers due to its microbicidal activities. Numerous applied researches about PAA have been reported in different fields [1], [2], [3], [4], [5], [6], [7], [8]. The increasing interest in PAA lies in its wide range of biocidal activity, in particular with respect to bacteria, algae, yeasts, moulds, fungi and viruses. But PAA solutions are also highly corrosive to any metals that are used in some appliances in family and hospital; this will result in serious economic loss.

Carbon steels are commercially available metals, which are used in the fabrication of reaction vessels, storage tanks, etc. Corrosion behavior of steels is mainly investigated in inorganic acids [9], [10], salts [11], non-oxidation organic acids [12], alkaline solutions [13], and marine media [14], [15]. But little has been studied about the corrosion mechanism of carbon steel in the presence of PAA solutions. Pehkonen et al. [16] have investigated corrosion of stainless steels in ozone and peracetic acid, their results showed that the corrosion rates in PAA solutions were lower than in ozone solutions, they deemed the corrosion behavior of stainless steel in PAA was unknown. However, it is important and helpful for us to know the corrosion mechanism in order to exploit high-efficient inhibitors in PAA solutions.

In the present work, the corrosion behavior of cold rolled steel in PAA solutions is investigated by the electrochemical method. Effects of the concentration of PAA and temperature on the corrosion rate are also investigated. Moreover, the spectra of PAA and the corroded surface of cold rolled steel in PAA solutions are characterized by Fourier transform infrared spectroscopy in order to analyze the adsorption behavior of PAA on the surface of cold rolled steel. A probable corrosion mechanism is presented to explain the related experimental results.

Experimental results

Fig. 1, Fig. 2, Fig. 3, Fig. 4 present the potentiodynamic polarization curves of cold rolled steel exposed to different concentrations of PAA solutions at test temperatures of 0 °C, 10 °C, 20 °C and 30 °C, respectively. With increasing of the concentration, the curves are shifted to high current density region and remain essentially the same. It is easy to see from the nature of these curves that active corrosion behavior is exhibited at each temperature and concentration of PAA solution. The

Conclusion

1.
PAA can accelerate the corrosion of cold rolled steel obviously, and the corrosion rate increases with increasing of the concentration of PAA. Concentrations of PAA and test temperatures fundamentally influence the corrosion of cold rolled steel. But the corrosion rate at 30 °C is less than that at 20 °C and bigger than that at 10 °C and 0 °C for each concentration of PAA.
2.
The Fe³⁺ ions are the dominant corrosion products dissolved in PAA solutions.
3.
The probable mechanism of the corrosion is assumed

Synergistic inhibition effect of Mikania micrantha extract with KI on steel corrosion in H<inf>2</inf>SO<inf>4</inf> solution
2021, Journal of Molecular Liquids
Mikania micrantha extract (MME) was prepared by reflux extraction method with 40% C₂H₅OH water solution. The synergistic inhibition effect of MME and potassium iodide (KI) on cold rolled steel (CRS) in 0.50 M H₂SO₄ solution was studied by weight loss and electrochemical methods for the first time. The CRS surfaces were fully characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). Meanwhile, the main effective compounds in MME were discussed in depth by high performance liquid chromatography (HPLC). The results show that either MME or KI acts as a moderate inhibitor on CRS in 0.50 M H₂SO₄ solution, and the maximum inhibition efficiency is below 80%. The mixture of MME/KI has a pleasant inhibition performance with the maximum inhibition efficiency of 94.4%. There is an evident synergistic effect between MME and KI, and the corresponding synergism parameter is higher than 1. Regardless of the extra addition of KI, the adsorption of MME obeys the Langmuir adsorption isotherm. The presence of KI enhances the adsorption of MME owing to larger value of adsorption equilibrium constant for MME/KI mixture. MME is a cathodic inhibitor, while MME/KI can be arranged as a mixed-type inhibitor, and the inhibition of both cathodic and anodic reactions is further enhanced by the MME/KI combination. Nyquist diagram mainly exhibits a capacitor loop that is controlled primarily by charge transfer. As the concentration of corrosion inhibitor increases the capacitance arc length gradually increases, especially for MME/KI mixture. The charge transfer resistance increases more than 10 times and shows excellent corrosion inhibition. SEM and AFM clearly confirm that the presence of MME/KI has a significant effect on inhibiting the corrosion of CRS, and the inhibition is expected to follow the order: MME/KI > KI > MME. XPS reveals that the MME/KI mixture can adsorb on steel surface to achieve inhibitive film. Most important, there is also a synergistic inhibition of effective components in MME (chlorogenic acid, ferulic acid) with KI.
Synergistic inhibition effect of walnut green husk extract and potassium iodide on the corrosion of cold rolled steel in trichloroacetic acid solution
2020, Journal of Materials Research and Technology
Plant extract inhibitor is of low price, rich natural raw resources, eco-friendly and biodegradable. To further strengthen inhibition stability and efficiency, halide ion is always mixed with plant extract so as to produce synergism. In the present work, the synergistic inhibition effect of walnut green husk extract (WGHE) and potassium iodide (KI) on the corrosion of cold rolled steel (CRS) in trichloroacetic acid (Cl₃CCOOH) solution was studied by weight loss, electrochemical techniques and surface analysis. Results show that WGHE moderately inhibits the corrosion of CRS in Cl₃CCOOH media. However, WGHE/KI mixture has pleasant inhibitive ability with the maximum inhibition efficiency of 97.2% in 0.10 M Cl₃CCOOH from weight loss method. There is a synergism for WGHE mixing with KI, and all corresponding synergism parameters are high than unity. The adsorption of WGHE either in the absence or presence of KI obeys Langmuir adsorption isotherm, and the external addition of KI facilitates the adsorption of WGHE on steel surface. Individual WGHE mainly retards cathodic reaction, while WGHE/KI mixture drastically inhibits both anodic and cathodic reactions simultaneously. Nyquist appears a capacitive loop at high frequencies followed by an inductive loop at low frequencies. The charge transfer resistance follows the order: WGHE/KI > KI > WGHE. SEM and AFM clearly proves the corrosion degree and surface roughness of CRS surface were dropped to more extent with the synergistic WGHE/KI mixture. Moreover, the synergistic inhibition of two main components of juglone and kaempferol with KI was discussed in detail under same conditions.

FTIR spectrum of the corrosion layer formed on CRS surface after 6 h immersion in 3.0 M H3PO4 is shown in Fig. 12(a). The weak band at 3751 cm−1 can be attributed to Fe–O bending [92]. The strong absorption band at 3438 cm−1 is attributed to O—H stretching.
The synergistic inhibition effect of walnut green husk extract (WGHE) and sodium lignosulfonate (SLS) on the corrosion of cold rolled steel (CRS) in 3.0 M H₃PO₄ solution was firstly studied by weight loss, electrochemical technique, surface analysis, quantum chemical calculation and molecular dynamics (MD) simulation. Results show that WGHE acts as a moderate inhibitor with a maximum inhibition efficiency of 73.4%, while SLS is poor inhibitor with the maximum inhibition below 40%. Mixing WGHE with SLS produces strong synergistic inhibition effect, and can significantly improve the inhibitive performance with a pleasant maximum inhibition efficiency of 97.2%. The synergism parameter is high than unity, and increases with the inhibitor concentration, but decreases with an increase of temperature. The adsorption of WGHE, SLS or WGHE/SLS obeys Langmuir adsorption isotherm. Individual WGHE or SLS mainly retards cathodic reaction, while WGHE/SLS mixture drastically inhibits both anodic and cathodic reactions simultaneously. The charge transfer resistance is drastically increased for the WGHE/SLS mixture, but the double electric capacitance decreases to more extent. The inhibited CRS surface by WGHE/SLS clearly appears little corrosion from SEM graph, and is of hydrophobic nature with an obtuse contact angle. Two components of naphthoquinone and 2-phenylchromone in WGHE exhibit synergistic inhibition with SLS. Quantum chemical calculations are well accordance with the expected inhibition order of WGHE/SLS > WGHE > SLS. The WGHE/SLS hybrid co-adsorb on Fe (001) and Fe (110) surfaces in the nearly flat manner, and the adsorption energy is more negative comparing with individual WGHE or SLS.
Inhibition performance of a multi-sites adsorption type corrosion inhibitor on P110 steel in acidic medium
2019, Chemical Physics Letters
In this work, a multi-site adsorption inhibitor (DBI) was synthesized and characterized. The corrosion inhibition performance of symmetric benzyl lauric acid imidazoline quaternary ammonium salt under 1 M hydrochloric acid (HCl) condition was studied by weight loss test, potentiodynamic polarization curve and electrochemical impedance spectroscopy (EIS), SEM and XRD techniques. The experiment results have shown that the inhibition efficiency increases with an increase in an inhibitor concentration. Potentiodynamic polarization showed that this inhibitor is an anodic-type inhibitor. It is proved that the corrosion inhibitor has high surface properties and good adsorption performance on the surface of P110 steel through the contact angle and surface tension test. Furthermore, the adsorption of the corrosion inhibitor conforms to the Langmuir's adsorption isotherm on the surface of P110 steel.
Synthetic lipids as a biocide candidate for disinfection of ballast water
2018, Marine Pollution Bulletin
The objective of this study is to propose the use of specific synthetic lipid as an active substance (biocide) in the control of harmful aquatic microorganisms, such as pathogens and non-indigenous species, transported in ships' ballast water. The biocide candidate, without metal or halogen components, was produced from a sub-product of the edible oil industry, the lecithin. Laboratory assays were conducted with phytoplankton, zooplankton, and marine bacteria to evaluate the efficiency of the biocide. The study also considers specific biocide's characteristics related to environmental risks, such as chemical composition, persistence, bioaccumulation, and toxicity. Results showed that, in the first 24 h of treatment, the biocide effectively reduced the concentration of the planktonic micro-organisms to very low levels. Additionally, a preliminary risk evaluation pointed that biocide candidate has a low residual toxicity, also a low potential for persistence and bioaccumulation in the environment.
Inhibition effect of bamboo leaves extract on cold rolled steel in Cl<inf>3</inf>CCOOH solution
2017, Journal of Materials Research and Technology
The corrosion inhibition by Dendrocalamus brandisii leaves extract (DBLE)/major flavonoid of cold rolled steel (CRS) in trichloroacetic acid (Cl₃CCOOH) solution was investigated by weight loss, electrochemical techniques and atomic force microscope (AFM). The adsorption mode of four major compounds (rutin, vientin, isovientin and orientin) on Fe (001) surface was theoretically investigated by molecular dynamics (MD). The results show that DBLE is a good inhibitor, and the maximum inhibition efficiency is higher than 95%. The adsorption of DBLE on CRS surface obeys Langmuir isotherm with exothermic process. DBLE behaves as a mixed inhibitor. AFM results confirm that DBLE could retard the corrosion of CRS in Cl₃CCOOH. The inhibitive action of each flavonoid is lower than DBLE, and follows the order: rutin > vientin > isovientin > orientin. The major flavonoids in DBLE are adsorbed onto Fe (001) surface through FBS (flavones backbone structure) with a nearby flat orientation.
