Abstract
Abstract A newly benzimidazole derivative, 1-butyl-3-methyl-1 H -benzimidazolium iodide (BMBIMI), has been tested as inhibitor for mild steel in 0.5 M H 2 SO 4 solution via various approaches including weight loss, electrochemical measurements, scanning electron microscope (SEM), atomic force microscope (AFM) and theoretical calculations. The obtained results reveal that BMBIMI is an effective mixed-type corrosion inhibitor for mild steel, and the adsorption of BMBIMI on the mild steel surface is found to obey the Langmuir adsorption isotherm, thus the thermodynamic and kinetic parameters governing the adsorption process are calculated and discussed. Moreover, theoretical calculations give further insight into the mechanism of inhibition of BMBIMI.
