SIDDIQUE, W.A.. Inhibiting Effect of Tetra-n-Butylammonium Iodide on the Corrosion of Mild Steel in Acidic Medium. []. , 25, 4, pp.443-452. ISSN 0872-1904.

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.
