Abstract EN
The corrosion inhibition effect of N-(4-((4-Benzhydryl piperazin-1-yl) methyl Carbamoyl) Phenyl) Furan-2-Carboxamide (BFC) on brass in 1M HCl has been investigated using weight loss method, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and cyclic voltammetry (CV).
The result reveals that BFC acts as a mixed type corrosion inhibitor with more pronounced effect on anodic domain and the inhibition efficiency of BFC increases with increase in temperature ranges from 30°C to 60°C.
AC impedance implies that Rct value of BFC increases with increase in concentration.
CV indicates that the addition of inhibitor controls the oxidation of the copper on the brass metal.
The structural confirmation of BFC was carried out by the spectral studies like FT-IR, 1H NMR, 13C NMR, and the molecular weight was confirmed by LC-MS.
Surface characterization of brass with BFC was analysed using scanning electron microscope (SEM).
Quantum chemical parameter was used to calculate the electronic properties of BFC in order to confirm the correlation between the inhibitor effect and molecular structure of BFC.
BFC has more negative charge on nitrogen and oxygen atom, which facilitates the adsorption of BFC on the surface of brass.
