    • Abstract

       

      Magnetite@carbon (Fe$_3$O$_4$@C) composites were prepared using three kinds of Fe$_3$O$_4$ nanoparticles (NPs). All the Fe$_3$O$_4$@C composites could be easily separated from water by an external magnet. The Fe$_3$O$_4$ NPs synthesized by a microreactor system have the smallest size and narrowest size distribution among the three kinds of Fe$_3$O$_4$ NPs. The saturated capacity of the Fe$_3$O$_4$@C composite originating from microreactor-prepared Fe$_3$O$_4$ NPs to absorb Rhodamine B at 20$^{\circ}$C exceeds 135 mg g$^{−1}$, which is 1.35 times as much as the value of the Fe$_3$O$_4$@C composite originating from traditional Fe$_3$O$_4$ NPs. This value for the Fe$_3$O$_4$@C composite using commercial Fe$_3$O$_4$ NPs as core is only 76 mg g$^{−1}$. The Fe$_3$O$_4$@C composite using microreactor-prepared Fe$_3$O$_4$ NPs also has good retrievability and reusability
