Abstract EN
Implementation of linear alkyl benzene sulphonate, LAS, as corrosion inhibitor on the surface of iron metal in acidic media and in the absence and presence of magnetic field has been investigated.
Adsorption of inhibitor molecules on iron surface showed Langmuir adsorption isotherms fit in acidic media.
In the absence of magnetic field, apparent activation energy values (Ea) in 2.0 M HCl solutions provide evidence of the inhibitory effect of LAS on iron; similarly, the enthalpy of activation values (ΔH≠) was in accordance with activation energy values.
Apparent entropy of activation shows that at larger inhibitor concentration, solvent entropy decrease in 1.0 M HCl and solvent entropy increase in 2.0 M HCl were obtained.
Furthermore, spontaneity, through equilibrium constant (Kads.) values and free energy value (ΔGads.) of the adsorption process, shows a drastic decrease upon temperature increase.
In the presence of magnetic field, lower rates of corrosion, larger activation energies, solvent entropy increase, larger equilibrium constant (Kads.) value, and lower free energy value (ΔGads.) have been investigated.
