The present invention relates to a water-treating graphene composite comprising at least one metal oxide including titanium oxide and at least one metal oxide including Fe 3 O 4 functionalized with the hollow spherulgraphite oxide, and a process for producing the same. The graphene complex for water treatment according to the present invention can treat not only heavy metals such as As, Pb and Hg but also decomposition of organic materials by the action of photocatalyst, and graphene oxide forming hollow spheres has high specific surface area , Since it has mechanical strength, it is possible to increase the removal efficiency of heavy metals, and furthermore, to have high light transmittance and high activity of photocatalyst. |
