More Details: The inhibition effectiveness of diverse concentrations of Datura Fruit Extract (DFE) on the corrosion of zinc in 0.05–0.1 M HCl solutions was examined by weight loss (WL), Electrochemical Impedance Spectroscopy (EIS), potentiodynamic polarization (PDP), and surface analysis techniques. The mass loss method's results demonstrated that raising the DFE concentration improved the efficiency of the inhibition. The maximum inhibition efficiency was 99.40% at 2.0 g/L of DFE. In the temperature ranging from 303 to 333 K, the effect of temperature on the corrosion behavior while adding DFE was also investigated. A DFE extract had been adsorbed on the surface of the metal by Langmuir adsorption isotherm models. It was established that the DFE's activation parameters and negative Gibb's free energy show that rates of adsorption have been spontaneous. According to polarization analysis, DFE regulates both the cathodic and the anodic response. Images obtained using a SEM (Scanning Electron Microscope) reveal that the DFE reduces surface damage. The adsorption inhibition mechanism is supported by the AFM analysis findings. FT-IR (Fourier transform infrared) spectroscopy has been utilized to ascertain the functional group of the DFE. All of the applicable approaches' experimental findings are in good agreement.
