Acid Corrosion Inhibition of Nickel by Some Organic/Macrocyclic Compounds
Abstract
The corrosion inhibition of nickel in 0.5 M sulfuric acid solution by 2-(triphenyl phosphoranylidene) succinic anhydride (2TPSA),1,4,8,11 tetraazocyclotetradecane (cyclam), and N, N′-bis(2-aminoethyl)-1,3-propane diamine (2,3,2 tet.) have been investigated using DC polarization technique.
The anodic polarization curves of nickel in 0.5 M H2SO4 at different concentrations of the three inhibitors were recorded at room temperature. The critical current density values were used to calculate the percentage inhibition for each inhibitor concentration. The results were compared with fits obtained from the application of Langmuir, Frumkin, Flory-Huggins isotherm, and also from the application of kinetic-thermodynamic model. The results obtained were correlated to the chemical structure and the macrocyclic effect of the inhibitors.
