Inhibitory Effect Of Some Oc —Aminocarboxylic Acids On Corrosion Of Aluminium In Hydrochloric Acid Solution
MetadataShow full item record
The corrosion of metallic aluminium in 2N hydrochloric acid solution in the presence of L-alanine, L-tyrosine, L-histidine and L-tryptophan as corrosion inhibitors has been studied using hydrogen evolution and thermometric methods. The two methods gave similar results. The inhibitory character of these compounds depends upon the concentration of the inhibitor, and their chemical structures. The adsorption of these additives on aluminium was found to obey the Frumkin adsorption isotherm.
