Superior adsorption of 3D nanoporous architectures for Ni(<scp>ii</scp>) ions adsorption using polyvinyl alcohol as cross-linking agent and adsorption conveyor

Abstract

was achieved for 3D nanoporous structure, which was 18-fold more than that for carbon nanotube powders and much higher than that for other sorbents reported in literature. In addition, it was found that 3D nanoporous architectures remained intact after adsorption, which could recollect resources and avoid carbon nanotube leakage into water. Therefore, the designed 3D nanoporous architectures have a good potential application in environmental protection.
