Abstract EN
The newly synthesized aminocyclohexane-N′-methylurea Mannich base was characterised using FT-IR, H1NMR, and C13NMR spectra and also it was tested as corrosion inhibitor for the mild steel in 1 N sulphuric acid.
Inhibitive study of this compound was carried out by weight loss method over the temperature range of 303–333 K, potentiodynamic polarisation, and AC impedance methods.
The inhibition efficiency was increased with increasing concentration of inhibitor whereas it was decreased with increasing temperature.
Potentiodynamic polarisation study showed that ACMU is a mixed type inhibitor.
AC Impedance study reveals that the corrosion of steel was mainly controlled by a charge transfer process.
Surface analysis was carried out using SEM technique.
The adsorption of inhibitor follows the Tempkin and Langmuir adsorption isotherms.
The activation energy (Ea), free energy change (ΔGads), enthalpy change (ΔHads) and entropy change (ΔSads) were calculated to understand the corrosion inhibition mechanism.
