PURPOSE: A graphene oxide sponge, a manufacturing method, an adsorbent including the same, and an adsorption method are provided to have an economical manufacturing process, and to effectively adsorb organic materials by being dispersed in an aqueous solution by using the sponge. CONSTITUTION: A manufacturing method of a graphene oxide sponge includes a step of manufacturing the graphene oxide sponge by centrifugally rotating a solution in which graphene oxide sheets are dispersed in the vacuum condition less than the normal pressure. Anion oxygen functional groups are bound to the surface of the graphene oxide sheets. The solution is an aqueous solution. The manufacturing method is processed in a tube. A graphene oxide sponge is manufactured on a side wall of the tube by the centrifugal rotation. |
