Investigation of ammonium (2,4-dimethylphenyl)-dithiocarbamate as a new, effective corrosion inhibitor for mild steel

Add time:07/13/2019    Source:sciencedirect.com

Methyl substituted phenyl containing dithiocarbamate compound has been investigated as corrosion inhibitor against steel corrosion in 1 M HCl solution. The inhibitor (namely ammonium (2,4-dimethylphenyl)-dithiocarbamate) offers extra stability and higher inhibition efficiency when compared to previously reported dithiocarbamate family inhibitors against steel corrosion. The inhibitor is able to adsorb on surface, by both physical and chemical means, while the methyl functionalized benzene ring produced hydrophobicity against the aqueous corrosive environment. For assessing the corrosion kinetics and inhibition mechanism, electrochemical impedance spectroscopy (EIS), potentiodynamic (PD) measurements and scanning electron microscopy (SEM) techniques were utilized.
