摘要：The present invention provides a method of preparing an iron oxide magneticnanoparticle, comprising the steps of: i) reacting a water-soluble ferrous salt with awater-soluble ferric salt in a mole ratio of 1:2 in the presence of a base and a citrate togive an iron oxide particle surface-coated with the citrate (c-MNP); ii) reacting the c-MNPobtained in step (i) with a thiophilic compound to give a thiophilic compound-boundediron oxide particle surface-coated with the citrate (thiophilic-c-MNP); and iii) modifying thethiophilic-c-MNP obtained in step (ii) using a surfactant for phase transfer of thethiophilic-c-MNP from aqueous phase to organic phase. The present invention alsorelates to the iron oxide magnetic nanoparticle prepared by the above-mentionedmethod and the use of the nanoparticle in desulfurization. The iron oxide magneticnanoparticle of the present invention is capable of effective deep desulfurization.
