Inhibiting Effect of Tetra-n-Butylammonium Iodide on the Corrosion of Mild Steel in Acidic Medium

Ver documento

Detalhes bibliográficos
Resumo:The inhibition effect of tetra-N-butylammonium iodide (TBAI) on mild steel in 1 N H2SO4 has been studied by using weight loss, electrochemical polarization, Fourier Transform Infrared (FTIR) and scanning electron microscopic (SEM) techniques. It has been concluded that the percentage inhibition increases with increasing the concentration of the inhibitor. The adsorption of TBAI on mild steel surface in 1 N H2SO4 obeys Langmuir adsorption isotherm; surface analysis and IR studies are also carried out to establish the mechanism of corrosion inhibition.
