摘要

The influence of the concentration of adenine (AD) on the corrosion of 304 austenic stainless steel inchloride acid solutions was studied. The investigations involved electrochemical polarization methods,scanning electron microscopy (SEM) and quantum chemical calculations method. Tafel polarizationstudy revealed that AD acted as a mixed-type inhibitor. The inhibition efficiency increased with anincrease in the concentration of adenine. The adsorption of AD has been found to occur on the surfaceof 304 austenic stainless steel according to the Langmuir isotherm. The kinetic and thermodynamicparameters for stainless steel corrosion and adenine adsorption, respectively were determined anddiscussed.
