dc.description.abstract |
Environmentally friendly three chitosan Schiff
bases (CSBs) were first time synthesized under microwave
irradiation by the reaction of chitosan and aldehydes
[benzaldehyde (CSB-1), 4-(dimethylamino)benzaldehyde
(CSB-2), and 4-hydroxy-3-methoxybenzaldehyde (CSB-3)]
and characterized by IR and NMR spectroscopy. The
corrosion inhibition performance of the synthesized inhibitors
was studied by the electrochemical impedance spectroscopy
(EIS) and potentiodynamic polarization (PDP). The results
show that all the Schiff bases (CSBs) act as effective corrosion
inhibitors for mild steel in 1 M HCl solution. Among the
synthesized Schiff bases, CSB-3 exhibited the maximum
inhibition efficiency of 90.65% at a very low concentration of 50 ppm. The EIS results showed that the CSBs inhibit corrosion
by the adsorption mechanism. The PDP results show that all the three Schiff bases are mixed-type inhibitors. The formation of
inhibitor films on the mild steel surface was supported by scanning electron microscopy/energy dispersive X-ray analysis and
Fourier-transform infrared spectroscopy methods. The adsorption of CSBs on the mild steel surface obeys the Langmuir
adsorption isotherm. The theoretical studies via density functional theory and molecular dynamics simulation corroborated the
experimental results. |
