Multi-step synthesis of core–shell magnetic nanoparticles bearing acid-chelating functional moieties

Résumé

Two synthetic approaches for the surface modification of core-shell-shaped silica coated magnetic nanoparticles with acid functions have been investigated. The step procedure based on the covalent attachment with diethylmalonate reagent and subsequent hydrolysis of the ester functions has proven to be much efficient and versatile for the incorporation of such functionality than the one-pot method. The changes in surface morphology and chemical functionality were examined by as X-ray diffraction (WAXD), infrared spectroscopy (FTIR), thermogravimetry analysis (TGA), zeta potential analysis and transmission electron
