Abstract :
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.
