Abstract
- The scrutiny of the impeding properties of vigna radiata (VR) on mild steel corrosion in sour environs (1 M HCl and 0.5 M H2SO4) was done by means of gravimetric, electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization methods (PDP). Polarization findings revealed that VR retarded the corrosion process in a mixedâmode manner. Adsorption of the active components of VR was found to be in line with Langmuir adsorption isotherm. The obtained PDP result was complemented by the EIS findings. Scanning electron microscopy (SEM), atomic force microscopy (AFM) and the theoretical technique was used to complement the results.
