Thermodynamic properties of Amino melamine Formaldehyde as corrosion inhibitor for steel in sulfuric acid solution

The corrosion inhibition of steel by amine melamine formaldehyde resin in different pH 4 and 6 from H2SO4 solution was studied at various temperatures (30,40,50) °C using electrochemical technique. The thermodynamic functions of dissolution and adsorption processes were calculated from experimental polarization data and the interpretation of the results are given. The apparent activation energies, enthalpy and entropy of the dissolution, process were determined and discussed.
