Molecular characterisation and corrosion studies of oligomer‐transition metals complexes
Abstract
Oligomer (semicarbaside‐phethalic acid) and its complexes with Fe(III), Co(II) and UO2(II) chloride were prepared and characterised using elemental analysis, spectral (1H NMR, infrared and UV‐Vis) and magnetic measurements. Extensive studies suggested that the Fe(III), Co(II), and UO2(II) oligomer complexes were octahedral dimers. Thermal analyses (thermal gravitational analysis (TGA) and differential thermal analysis (DTA)) of the complexes were carried out and the relevant activation energies were calculated. The effect of the oligomer on the corrosion of iron metal in acidic media (2 M H2SO4) was studied. It was found that the oligomer inhibited the corrosion of iron metal in acid media. The corrosion inhibition efficiency of these compounds was calculated based on weight loss and potentiostatic measurements.
