【 摘 要 】

In this study, Fe 3 O 4 @C submicron rods were successfully prepared by an oxalate thermal decomposition–glucose hydrothermal carbonisation process. The adsorption property of the Fe 3 O 4 @C submicron rods to methylene blue was researched. The results show that the adsorption process conforms to the Langmuir isotherm model and pseudo-second-order kinetic model. The Fe 3 O 4 @C submicron rods show a comparable adsorption capacity compared with Fe 3 O 4 @C nanoparticles, but their separation speed under an external magnetic field is much faster than that of Fe 3 O 4 @C nanoparticles. These make the Fe 3 O 4 @C submicron rods an ideal material for the adsorption of the organic contaminant from water.
