In this study, the inhibitive action of Acacia nilotica fruits powder towards the corrosion behavior of aluminium in 1.0M HCl and 1.0M NaOH solutions has been studied without carrying out any solvent extraction of the fruits powder using weight loss method. Acacia nilotica showed corrosion inhibition efficiency of 98.83 and 71.64% in HCl and NaOH respectively in the presence of 0.5% w/v inhibitor concentration at 318K. The activation energy increases from that of the blanks (23.84 and 49.25 kJmol-1) to the inhibited (55.92 and 65.92 kJ mol-1) in HCl and NaOH respectively. The adsorption process was spontaneous as indicated by the large negative values of and . The values of enthalpy were positive indicating endothermic process of adsorption. The adsorption of Acacia nilotica on aluminium was best fitted to Langmuir adsorption model in both media. The result of FTIR Spectra also indicated physisorption mechanism as proposed by the thermodynamic data.
