摘要：

In this work, we synthesized and characterized the magnetic graphene oxide (MGO) composite, and used it for the removal of Ni(II) from aqueous solutions as a high efficient and low-risk adsorbent. The results showed that the adsorption of Ni(II) on MGO is endothermic and spontaneous. The absorption of Ni(II) on MGO is strongly dependent on pH values due to the electrostatic interaction. The adsorption kinetic and isotherms were fitted the pseudo-second-order and Langmuir model well, respectively. The results also indicated that the combination of the excellent adsorption capacity of GO and the magnetic properties of Fe3O4 is extremely valuable, which has a good application prospect due to it has many advantages such as easy magnetic separation, excellent repeat-ability and environment-friend.
