“…To explore the effect of LFH on the initiation and development of corrosion at the Cu/solution interface, (AFM) has emerged as a promising new method (Anbarasi et al, 2012;Sherine et al, 2010;Singh et al, 2011;Wang et al, 2011). AFM image analysis was used to determine the root mean square surface roughness (Sq) and mean roughness (Sa) for copper surfaces immersed in different environments.…”

This study focused on the recycling of the expired Levofloxacin hemihydrate (LFH) for preventing copper (Cu) corrosion caused by synthetic acid rain (SAR) solution employing electrochemical techniques potentiodynamic polarization (Tafel Polarization) and electrochemical impedance spectroscopy (EIS); and chemical method (weight loss (WL)). Results showed that LFH is an efficient inhibitor for copper corrosion, and the inhibition efficiency percent (η%) reached 88.4 % at an optimum concentration (600 ppm) according to EIS measurements. The data of WL method revealed that the inhibition efficiency (η%) raised and the corrosion rate (k corr ) decreased with the concentration of LFH and vice versa with the temperature. It was discovered that the adsorption of the LFH on the Cu surface obeyed Langmuir adsorption isotherm. The Tafel curves demonstrated that this expired behaved as a mixed-type inhibitor. The LHF prevented corrosion by adhering to the metal surface, which was demonstrated by Scanning Electron Microscopy Conducted with Energy Dispersive X-ray (SEM-EDX), Atomic Force Microscopy (AFM), and Fourier Transform Infrared Spectroscopy (FT-IR).

The present study reports a sustainable source of lignin, from termite frass. Lignin was extracted using Klason’s method and subjected to polarization studies to check the inhibition efficiency and measured the electrochemical performance of the coated sample on the carbon steel using electrochemical impedance spectroscopy. The anticorrosive property was determined in a simulated corrosive environment (0.1 M NaOH and 0.5 M NaOH). The morphological analysis of the surface of both bare metal and the lignin-coated ones, before and after exposure to the corrosive environment, was recorded using atomic force microscopy (AFM), scanning electron microscopy (SEM), and energy-dispersive X-Ray spectroscopy (EDX). The lignin showed maximum inhibition efficiency at 600 ppm in 0.5 M NaOH solution. Moreover, the lignin coated on carbon steel exhibited about 70% corrosion inhibition efficiency as recorded by potentiodynamic polarization studies and electrochemical impedance spectroscopy. The AFM and SEM analyses further corroborated the protection of the metal surface from corrosion when coated with lignin. Hence, the study suggests lignin from termite frass as a sustainable biological source suitable for anticorrosive applications. Graphic abstract

“…of a condensation protective film on the carbon steel surface, which is responsible for inhibiting corrosion. It can be shown that the surface coverage increases, which in turn leads to the formation of an insoluble compound on the surface of the metal (Fe 2+ -CPHAQ2O complex), and the surface is covered with a thin layer of inhibitors that control the dissolution of solid carbon [19][20][21].…”

The inhibition ability of the new derivative (quinolin-2-one), namely (1-{[5-(2-Chloro-phenylazo)-2- hydroy-benzylidene]-amino}-4,7-dimethyl -6-nitro- 1H-quinolin-2-one (CPHAQ2O)) towards carbon steel corrosion in (3.5% NaCl) and (0.5M HCl) solutions were evaluated by potentiodynamic polarization at different inhibitor concentrations. Polarization curves showed that the evaluated compound acted as mixed inhibitors, and the adsorption of the evaluated inhibitor obeys the Langmuir adsorption isotherm in both salt and acid solutions. The results revealed that the percentage inhibition efficiency (%IE) in the salty solution (90.55%) is greater than that in the acidic solution (77.62%). The surface changes of the carbon steel and the film persistency of the inhibitor were studied using SEM (Scanning Electron Microscopy).
