Tan, Bochuan published the artcileExperimental and theoretical studies on the inhibition properties of three diphenyl disulfide derivatives on copper corrosion in acid medium, Category: catalysis-chemistry, the publication is Journal of Molecular Liquids (2020), 111975, database is CAplus.
2,2′-Dithiosalicylic acid (DSA), 2-aminophenyl disulfide (APD) and 2,2-dibenzamidodiphenyl disulfide (DPD) were determined for corrosion inhibition of Cu in H2SO4 media by electrochem. tests, surface morphol. anal., quantum chem. calculations and mol. dynamics simulations. The results of polarization curves showed that DSA, APD and DPD reveal good anti-corrosion capacity. They can simultaneously inhibit the cathodic and anodic reactions of copper. Therefore, they belong to the mixed-type corrosion inhibitors. Impedance spectroscopy results showed that when DSA, APD and DPD adsorption on the surface of Cu, the charge transfer resistance increases significantly and typical capacitance behavior produced, which indicates that the formed inhibitor film is very dense and ordered. In addition, the adsorption of corrosion inhibitors on the Cu surface is conforming to Langmuir monolayer adsorption. The exptl. results obtained by surface topog. anal. are consistent with the results of electrochem. experiments Their corrosion inhibition ability is DSA < APD < DPD. Theor. calculations further explore the relationship between corrosion inhibition performance and their mol. configurations.
