Nickel-metal-organic framework nanobelt based composite membranes for efficient Sr²⁺ removal from aqueous solution.

ABSTRACT: The sorption removal of radionuclides Sr²⁺ using a freestanding functional membrane is an interesting and significant research area in the remediation of radioactive wastes. Herein, a novel self-assembled membrane consisting of metal-organic framework (MOF) nanobelts and graphene oxides (GOs) are synthesized through a simple and facile filtration method. The membrane possesses a unique interwove morphology as evidenced from SEM images. Batch experiments suggest that the GO/Ni-MOF composite membrane could remove Sr²⁺ ions from aqueous solutions and the Sr²⁺ adsorption capacity and efficiency of the GO/Ni-MOF composite membrane is relevant to the MOF content in the composite. Thus, the dominant interaction mechanism was interface or surface complexation, elec
