“…Recently, eco-friendly and biodegradable commodities have caused a shift towards the use of natural product instead of using toxic materials [1]. Furthermore, natural products derived from various flora and fauna are believed to be safe due to their nontoxic, noncarcinogenic, and biodegradable nature [2][3][4]. Heavy metals such as lead (Pb) which are produced from industry (painting, charcoal burning, and leaded gasoline) are known to be a threat to the marine environment [5].…”

Lawsonia inermis also known as henna was studied as a corrosion inhibitor for aluminum alloy in seawater. The inhibitor has been characterized by optical study via Fourier transform infrared spectroscopy (FTIR). The FTIR proves the existence of hydroxyl and carbonyl functional groups in Lawsonia inermis. Aluminum alloy 5083 immersed in seawater in the absence and presence of Lawsonia inermis was tested using electrochemistry method, namely, electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PP). EIS and PP measurements suggest that the addition of Lawsonia inermis has caused the adsorption of inhibitor on the aluminum surface. The adsorption behavior of the inhibitor follow Langmuir adsorption model where the value of free energy of adsorption, -ΔG, is less than 40 kJ/mol indicates that it is a physical adsorption. Finally, it was inferred that Lawsonia inermis has a real potential to act as a corrosion inhibitor for aluminum alloy in seawater.

“…It is very important to add a corrosion inhibitor to decrease the rate of aluminum dissolution in such solutions [1][2][3]. So, numerous researches used organic compounds containing heteroatom such as O, N, and S as a corrosion inhibitors of aluminum in acidic solutions [4][5][6][7][8][9][10]. In the present work, the corrosion inhibition of aluminum in 0.5 M HCl solution was investigated by imidazole derivatives using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation (EFM) methods.…”

Introduction The inhibition performance of three peels, for instance Pisum sativum (PS), Solanum tuberosum (ST), and Citrus reticulata (CR), on aluminum alloy (AA) in 1 M NaOH solution was investigated using weight loss, electrochemical impedance spectroscopy (EIS), linear polarization, and potentiodynamic polarization techniques (Tafel). Results It was found that these three peel extracts exhibit very good performance on AA in alkaline medium. PS exhibited maximum inhibition efficiency (g%) of 94.5 % at 1.5 g/L. The effective protection of AA in inhibited system was investigated using scanning electron microscopy (SEM) and atomic force microscopy (AFM). Conclusion The adsorption of inhibitors on AA surface obeyed the Langmuir's adsorption isotherm. Potentiodynamic polarization studies showed mixed mode of corrosion inhibition for all the inhibitors. SEM and AFM complemented well with those obtained from weight loss and electrochemical studies.
