Objectives: To use the newly synthesized efficient organic corrosion inhibitor N-(4-((4-(pyridin-2-yl) piperazin-1-yl)methyl)phenyl)quinoline-6-carboxamide to carry out on mild steel corrosion inhibition study. Methods: N-(4-((4-(pyridin- 2-yl)piperazin-1-yl)methyl)phenyl)quinoline-6-carboxamide was synthesized by stirring method under 0oC to room temperature at 12 hrs. The synthesized organic inhibitor was characterized by 1H NMR, 13C NMR, UV and FTIR spectroscopy. The inhibition effect of organic inhibitor on the mild steel corrosion was investigated with weight loss measurement by gold measuring weighing balance. The inhibitor anchored down on the mild steel surface was analyzed by scanning electron microscopy and Atomic Force Microscopy. Findings: The inhibitor shows a better inhibition efficiency of maximum 74.41% in 1N HCl medium. In addition to this adsorption isothermal models were also interpreted to fit the adsorption behavior of the inhibitor compound on mild steel surface. Thus, the result shows the Langmuir adsorption isotherm. As a result, the interactions between inhibitor and mild steel surface have chemisorptions. Novelty: The N-(4-((4-(pyridin-2-yl) piperazin-1-yl)methyl)phenyl)quinoline-6-carboxamide shows better corrosion inhibition efficiency (74.41%). In addition, inhibitor and mild steel surface show chemisorptions interaction, which confirms free energy and enthalpy of adsorption.
