Studying the corrosion inhibition of carbon steel in hydrochloric acid solution by 1-dodecyl-methyl-1H-benzo[d][1,2,3]triazole-1-ium bromide

Abstract

A novel cationic surfactant with good surface properties as a good inhibitor for carbon steel in HCl is shown, acting as a mixed-type inhibitor. Its adsorption obeys the Langmuir isotherm. By increasing the inhibitor concentration the inhibition efficiency increases.
