Abstract
The inhibition efficiency of adipic acid in control ling corrosion of Aluminium in an aqueous solution at pH 10, in the absence and presence of Zn 2+ has been evaluated by weight loss method. The form ulation consisting of 250 ppm of adipic acid and 50 ppm of Zn 2+ has 98% corrosion inhibition efficiency. A synergi stic effect exits between adipic acid and Zn 2+ . The protective film has been analyzed by UV-vi sible absorption spectroscopy and Fluorescence spectra
