Objectives: To use the newly synthesized efficient organic corrosion inhibitor 1-[(4-nitrophenyl)methyl]-4-(pyridin-2-yl)piperazine (NMPP) to carry out on mild steel corrosion inhibition study. Methods: The 1-[(4-nitrophenyl)methyl]-4-(pyridin-2-yl)piperazine (NMPP) organic inhibitor was synthesized by condensation polymerization. The organic inhibitor NMPP, was chara cterized by Fourier transform infrared (FTIR), and high resolution scanning electron microscope (HR-SEM). The inhibition action of the polymer composite was investigated by conventional weight loss method, and electrochemical impedance spectroscopy (EIS). Findings: The maximum corrosion inhibition efficiency of 88.34 % was obtained at concentration level of 6 % at 303K. The results revealed NMPP as a mixed type corrosion inhibitor, the thermodynamic and kinetic parameters also revealed adsorption of catalyst on to mild surface as exothermic and the adsorption was confirmed by conventional weight loss method. Novelty: FT-IR analysis reveals that predominant peaks are the interaction between inhibitor and mild steel surfaces. The morphology of mild steel coupons was investigated by HR-SEM. The HR-SEM results showed novel inhibitor to have inhibited corrosion on mild steel in 1 M HCL on CO2 environment.
Keywords: Novel inhibitor, Mild steel, HRSEM, NMPP and Corrosion Inhibition
