A Study on 4-(4-Aminobenzene-1-sulfonyl)piperazin-1-yl)(furan-2-yl)methanone for the Prevention of Corrosion on Mild Steel in Acidic Medium

Abstract

Synthesized [4-(4-aminobenzene-1-sulfonyl)piperazin-1-yl)(furan-2-yl)methanone (4-4-ABSPFM), a novel organic compound was used as inhibitor on prevention of mild steel corrosion. Experiments were performed in 1 N HCl acidic medium by weight loss method and electrochemical analysis. On comparing the results, it reveals that the novel organic compound shows better inhibition efficiency on mild steel corrosion, which is more effective in 1 N HCl at three different temperatures. Electrochemical studies such as AC impedance and potentiodynamic polarization studies were proven the results by showing the inhibitor is a mixed type inhibitor in acidic medium. From the semi-micrograph obtained from SEM analysis shows a better efficiency of the inhibitor over the surface of the mild steel.
