Toward 3D graphene oxide gels based adsorbents for high-efficient water treatment via the promotion of biopolymers

- 3D high-efficient GO based gels were prepared via the promotion of biopolymers.
- The obtained gels have interconnected 3D porous network and large adsorption capacity.
- The adsorption process to methylene blue was systematically studied and discussed.
- The GO-biopolymer gels showed good selective adsorbability to cationic dyes.
