摘要

In the present study, new magnetite nanoparticles coated with rosin amidoxime prepared to apply ascorrosion inhibitors for steel in 1 M HCl. Rosin midoxime was prepared from from hydrolysis of rosin-acrylonitrile Diels Alder adduct using hyroxylamine in basic medium. A new monodisperse magnetitenanoparticles was prepared by a simple and inexpensive co-precipitation method followed by cappingwith rosin amidoxime. The chemical structure, particle size and morphology of magnetite capped withrosin amidoxime were characterized by Fourier transform infrared spectroscopy (FTIR), transmissionelectron microscopy (TEM), and dynamic light scattering (DLS). Corrosion protection properties ofmagnetite-RK/amidoxime nanoparticles on steel in hydrochloric acid have been studied by polarizationand electrochemical impedance spectroscopy (EIS). The results show that magnetite-RK/amidoximenanoparticles. acts as good inhibitor and inhibition efficiency (%IE) increases with inhibitorconcentration. Potentiodynamic polarization measurements indicated that magnetite-RK/amidoximenanoparticles. acts as a mixed type inhibitor. EIS results indicated that the charge transfer resistance(Rct) increases with magnetite-RK/amidoxime concentration. IE values obtained frompotentiodynamic polarization showed a reasonable agreement with those obtained from EISmeasurements.
