摘要：Inhibitive effect of Mentha pulegium extract on the acid corrosion of aluminum in 1 M HCl solution was studied using gravimetric, gasometric and EIS techniques. It was shown that the presence of acid extract of Mentha pulegium extract inhibited the corrosion of aluminum in the test solutions and the inhibition efficiency depended on the concentration of the plant extract as well as on the time of exposure of the aluminum samples in HCl solutions containing the extract. Effect of temperature on the corrosion behavior of aluminum in 1M HCl was also studied in the range 298 K and 318 K. The thermodynamic data of activation are determined. Mentha pulegium extract is adsorbed on the aluminum surface according to a Temkin adsorption model
