Abstract: Ficus sycomorus gum was tapped, collected and purified. The adsorption properties and inhibition potentials of the gum on aluminium in HCl was studied at different temperature of 303K and 333K using gravimetric method. The inhibition efficiencies of the gum increase with increase in concentration and decrease with increase in temperature and period of immersion. Values of activation energy of the inhibited corrosion reaction of aluminium were greater than the value obtained for the blank. Thermodynamic consideration revealed that adsorption of the inhibitor on aluminium surface was first order, exothermic, spontaneous and was through the mechanism of physical adsorption. The adsorption characteristic of the inhibitor was best described by the Langmuir adsorption isotherm.
