The inhibition effect of MGD (Malachite green dye) on the corrosion of mild steel was studied by weight loss, Potentiodymanic polarization and FTIR spectra. The absence and presence of Zn2+ was studied. MGD alone has some inhibition efficiency of 76%. Increasing the concentration of MGD and Zn2+, the efficiency has increases. The influence of the TSC (Trisodiumcitrate) on the corrosion inhibition ofMGD+Zn2+ systemwas studied and the IE is 100%. Present study was aimed to investigate the inhibition efficiency ofMGD-Zn2+-TSC in controlling the corrosion of carbon steel immersed in aqueous solution containing 60 ppmCl-. Potentiodymanic polarization study and FTIR shows that protective film formed on the metal surface.
