Adsorption of Some Aliphatic Carbonyl Compounds on Alumium from Acidic Chloride Solution

Abstract

The adsorption of acetone, ethyl methyl ketone, diethyl ketone and disodium salt of ethylene diamine tetraacetic acid on aluminium from acidic chloride solution has been studied using the corrosion technique. The corrosion rates of aluminium in acidic chloride solution containing carbonyl compounds are measured by weight loss and hydrogen evolution as a function of carbonyl compounds concentration. The degree of surface coverage is used to calculate the protection efficiency and the free energy of adsorption of the carbonyl compounds.
