摘要：The corrosion inhibition of mild steel in HCl acid solutions by some new triazole surfactants derivatives namely 2-(5- decylthio-3-methyl-1,2,4-triazole)acetic acid (MTSC10AC), 2-(5-undecylthio-3-methyl-1,2,4-triazole) acetic acid (MTSC11AC), 2-(5-dodecylthio-3-methyl-1,2,4-triazole) acetic acid (MTSC12AC) have been studied using electrochemical polarization method and electrochemical impedance spectroscopy measurements. These inhibitors have also been studied computationally using density functional theory (DFT). Observable correlation was found between corrosion inhibition efficiency and quantum chemical parameters, using the linear quantitative structure–activity relationship (QSAR) models.
