Fourier Transform Infrared Spectroscopic Analysis (FTIR) was used to characterize the inhibitor and the corrosion product. The effect of different inhibitor concentrations was studied at 308, 313 and 318 K. The present study showed that the percentage of inhibition efficiency (% I.E.) is enhanced with increase of inhibitor concentration and decrease with rising in temperature. Maximum I.E. of Anisaldehyde was found 86.32 % at 308 K and 0.1M inhibitor concentration in 1.4M HNO3 solution. The inhibitive action of the inhibitor is discussed in view of adsorption of Anisaldehyde molecule on the metal surface. It was found that the adsorption of the inhibitor on the metal surface follows Langmuir adsorption isotherm. Activation parameters governing the adsorption process were evaluated and discussed in detaienAluminum; Corrosion; Weight loss; FTIR analysis; Activation parameters; Adsorption isotherm.Article
