“…According to the data presented in Table 3, there is a noticeable disparity in the anodic and cathodic current densities following the introduction of a corrosion inhibitor. This discrepancy suggests that the lupine extract functions as a corrosion inhibitor with mixed type properties [37]. The data presented in Table 3 demonstrates a clear correlation between inhibitor concentrations and the reduction of icorr values.…”

The application of lupine extract in a 2 M sulfamic acid (H2NSO3H) solution effectively prevented copper corrosion. Various techniques were employed to conduct these experiments, including mass loss ML, dynamic potential polarization PL, and electrochemical impedance EIS. Theoretical calculations, such as DFT, Fukui function, and Monte Carlo simulations, were also utilized. FT-IR spectroscopy was utilized to analyze the surface composition of Cu. The shape of the Cu surface was determined using advanced nanotechnology techniques, specifically scanning electron microscopy (SEM). The investigation focused on the impact of Lupine extract on Cu corrosion in sulfamic acid at a temperature of 250C. The inhibition rate of Cu corrosion was assessed using mass loss (ML) as the primary measurement method. After conducting a thorough analysis of its interaction with copper surfaces, it was determined that the substance exhibits chemical adsorption characteristics and adheres to the Langmuir isotherm model. Upon examining the PL curves, it becomes evident that the Lupine extract functions as a mixed-type inhibitor. The effectiveness of inhibition was observed to rise as the concentration of Lupine increased. Furthermore, the findings demonstrate that increased temperatures have a detrimental impact on the effectiveness of inhibition. The density functional theory (DFT) and Monte Carlo simulation (MC) were utilized to compare the experimental results with the theoretical calculations.

The antibiotic Ciprofloxacin (CIPRO) was investigated as a new inhibitor for copper corrosion in Synthetic Acid Rain Solution (SAR) utilizing Mass Loss (ML) as a chemical method, Potentiodynamic Polarization (PDP), and Electrochemical Impedance Spectroscopy (EIS) as electrochemical techniques. In the presence of 600 ppm of the antibiotic CIPRO, the protection percentage reached 90.1% according to the EIS technique. Thermodynamic adsorption and activation characteristics were evaluated and described. The CIPRO adsorption on the Cu surface in the SAR solution was physical adsorption and complied with the Langmuir isotherm. According to PDP curves, the studied medication was served as a mixed type of inhibitor. This medication prevented corrosion by adhering to the metallic surface, which was demonstrated by Atomic Force Microscopy (AFM), Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM–EDX), and Fourier-Transform Infrared Spectroscopy (FTIR). Results from the Density Functional Theory (DFT) and Monte Carlo simulations (MC) complement experimental results. The inhibition efficiencies obtained via different methods are consistent with each other. Graphical Abstract
