This paper evaluated the possibility of using quinoline derivative (an expired Moxifloxacin) as an inhibitor for copper corrosion in synthetic acid rain (SAR) solution. Weight reduction (WR) experiments, potentiodynamic polarization (PDP) and AC impedance spectra (EIS) were employed to investigate corrosion inhibition (ƞ%) and inhibition rates. (ƞ%) increases by increasing the concentration of MOXI in all test methods. The PDP curves indicated that this expired medication exhibited mixed-type inhibitory activity. According to the EIS tests, the ƞ % was found to improve with raising the MOXI concentration and reached 94.05% at 600 ppm. On the other hand, the ƞ% was lowered by raising the temperature. The adsorbed MOXI molecules on copper obey Langmuir isotherm model. Furthermore, scanning electron microscopy (SEM), atomic force microscopy (AFM), and Fourier transform infrared spectroscopy (FT-IR) are employed to examine the surface of the copper sample. The results acquired experimentally were validated through the application of density functional theory (DFT) and molecular simulation (MC) in theoretical calculations. All the tests metthods gave similar results.

“…Instead of producing corrosive fumes, the −NH 2 and −OH functional groups in water solutions of sulfamic acid dissolve the incrustations so they can be removed. A corrosion inhibitor must be present in the sulfamic acid solution to stop corrosion from harming metal surfaces . The earliest metal that humans found and used is copper, which is widely used in a variety of industries, including manufacturing, national defense, light, electrical, and machinery.…”

Copper corrosion was suppressed when a lupine extract was immersed in a 2 M sulfamic acid (H 2 NSO 3 H) solution. Numerous methods, including mass loss (ML), dynamic potential polarization (PL), and electrochemical impedance (EIS), were employed in these experiments, in addition to theoretical computations such as density functional theory (DFT), Fukui function, and Monte Carlo simulations. Fourier transform infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM) were used to analyze the Cu surface’s composition and determine its form. Mass loss (ML) was used to examine the inhibition rate of copper corrosion in sulfamic acid at 25 °C in the presence of lupine extract. After examining how it behaved throughout the adsorption process on copper, it was discovered that it follows the Langmuir isotherm and chemical adsorption. An analysis of the PL curves indicates that the lupine extract is a mixed-type inhibitor. It was shown that the inhibitory efficiency increased to 84.2% with increasing lupine concentration. Additionally, as the data show, the efficiency of inhibitors is diminished by increasing temperatures. Theoretical calculations and experimental data were compared using Monte Carlo simulation (MC) and density functional theory (DFT).
