| Abstract | ||||
| The inhibitive action of the aqueous extract of Salvadore persica toward acid corrosion of aluminum is tested using weight loss, thermometry, hydrogen evolution, polarization techniques and FTIR spectroscopy. It was found that the extract acts as a good corrosion inhibitor for aluminum corrosion in 2M HCl solution. The inhibition action of the extract was discussed in view of Langmuir adsorption isotherm. It was found that the adsorption of the extract on aluminum surface is a spontaneous process. The inhibition efficiency (ƞ %) increases as the extract concentration is increased. The effect of temperature on the (ƞ %) was studied. It was found that the presence of extract increases the activation energy of the corrosion reaction. | ||||
