چکیده
|
The adsorption and inhibition effect of n,n,n- tributyl-1-butanaminiuiodide(tbai) on mild steel in 1m hcl at 298-328k was studied by potentiodynamic polarization, eis and atomic force microscopy techniques. the results showed that inhibition efficiency increases with inhibitor concentration. the adsorption of n,n,n- tributyl-1-butanaminiuiodide on mild steel surface obeys langmuir adsorption isotherm equation. both thermodynamic (enthalpy of adsorption δhads, entropy of adsorption δsads& free energy of adsorption δgads) and kinetic parameter (energy of activation ea, entropy of activationδs^0, enthalpy of activationδh^0) were calculated and discussed. polarization curves showed that the studied inhibitor acted as mixed type inhibitor.
