Iron oxide magnetic nano particle, preparation method and application method thereof in desulfurization |
| abstract |
The invention provides a method for preparing iron oxide magnetic nano particles, which comprises the following steps: i) reacting water-soluble ferrite with water-soluble iron salt according to a mol ratio of 1:2 in the presence of alkali and citrate, thus generating iron oxide particles of which the surfaces are coated with the citrate, namely c-MNPs; ii) reacting the c-MNPs obtained in the step i) with a compound containing a thiophilic element, thus preparing iron oxide particles which are combined with the thiophilic element and contain the citrate coated on the surfaces, namely thiophilic element-MNPs; and iii) modifying the thiophilic element-MNPs obtained in the step ii) with a surfactant, and transferring the thiophilic element-MNPs from a water phase into an organic phase. The invention also relates to iron oxide magnetic nano particles prepared by the method and a method for performing desulfurization by using the iron oxide magnetic nano particles. Deep desulfurization effect can be effectively realized by using the iron oxide magnetic nano particles provided by the invention. |
