“…Many researchers use plants to prepare inhibitors since plants are renewable materials and to prepare the extract requires inexpensive apparatus and chemicals with simple methodology. For instance, the results in [16] were used in preparing the extract of Curcuma xanthorrhiza at 1,000 ppm. The plant was extracted using 1M HCl with a single extraction method.…”

This work covers the effectiveness of the White tea extract as a green corrosion inhibitor and is correlated to the strength and stability bonding between the phenolic molecule and the Fe atoms in mild steel and how this interaction can be studied by altering the concentration and temperature. White tea has received considerable attention due to its capability as a corrosion inhibitor and has been extensively studied using electrochemical techniques. However, accurate and systematic functional group identification and surface modification have been missing. Our study sought to demonstrate the quantitative measurement of electrochemical impedance spectroscopy (EIS) complemented by the FTIR (Fourier transform infrared spectroscopy), Total Phenolic Test, and Raman Spectroscopy. The SEM (Scanning Electronic Microscope)/EDX (Energy-Dispersive X-Ray Spectroscopy), and AFM (Atomic Force Microscope) were used to study the surface modification. The EIS results show that the optimum inhibition efficiency was 96 % in a solution of 80 ppm at 60 °C. Acetone 70 % was used to extract White tea and gives 14.17±0.25 % phenolic compound. Spectroscopic studies show -OH, Aromatic C=C, C=O and C-O-C become major contributors in the adsorption process and are found on the surface of metals as corrosion protection. Meanwhile, the thermodynamic calculation shows the White tea was adsorbed chemically. The nearness of R2 to 1 shows the adsorption agrees with the Langmuir adsorption isotherm. Eventually, the surface modification revealed that phenol molecules are responsible to reduce the corrosion rate at 16.38×10-3 mpy. Our results are expected to provide a guideline for future research in White tea as a green corrosion inhibitor

The corrosion inhibition efficiency of Rhizophora acipulata(RA) extract was investigated for API 5L Steel corrosion in 3.5% NaCl using weight loss and polarization method. Fourier Transform Infra-Red (FTIR) was used toanalyze the characteristics of extract RA functional groups. The weight loss and polarization result indicated that extract RA inhibited API 5L steel corrosion rate. Based on the polarization result, the inhibition efficiency reached up 97.52% with addition 100ppm of RA extract.

“…They reported that the active molecules of the extract adsorbed on the mild steel obey the Langmuir adsorption isotherm as the inhibitor affects the cathodic and anodic regions. The work of [10] reveals that in the presence of Curcuma xanthorrhiza extract, the API 5L X42 steel corrosion rate is remarkably reduced through weak electrostatic interaction between the adsorbate and substrate. Similar to the previous study, the inhibition adsorption mechanism follows the Langmuir adsorption isotherm.…”

This work reports the anti-corrosion behavior of liquid smoke from rice husk ash to unveil the contribution of its active compounds in 1 M HCl solution. In this study, the developed methodology to test, analyze, and model the novel type of green corrosion inhibitor for C1018 was characterized using Electrochemical impedance spectroscopy (EIS), Potentiodynamic polarization, and deep learning methods. The inhibitor structure was characterized by Fourier transform infrared analysis (FTIR) and Ultraviolet–visible spectroscopy (UV-Vis). The surface characterization of mild steel immersed in blank and 80 ppm solution inhibitor was performed using Atomic force microscopy (AFM) analysis. The corrosion test results show that the inhibitor is considered a mixed-type inhibitor to achieve the optimum inhibition of 80 ppm at 323 K, reaching up to 99% inhibition efficiency. The AFM results show a smoother surface given a lower skewness parameter at −0.5190 nm on the treated mild steel. The artificial neural network demonstrates the lower overfitting on the inhibited steel, a higher accuracy prediction of 81.08%, and a lower loss rate of 0.6001 to model the relationship between the EIS and Potentiodynamic polarization and the evolution of the passive layer on the treated mild steel. The experiment agrees well with the prediction result to model the adsorbed inhibitor. The work can be used as a guideline to pave the way for subsequent applicability in developing green corrosion inhibitors based on experimental and artificial intelligence approaches.
