摘要
Presence of emerging organic contaminants(EOCs)in water is one of the major threats to water safety.In recent decades,an increasing number of studies have investigated new approaches for their effective removal.Among them,metal-organic frameworks(MOFs)have_attracted increasing attention since their first development thanks to their tunable metal nodes and versatile,functional linkers.However,whether or not MOFs have a promising future for practical application in emerging contaminants-containing wastewater is debatabie.This review summarizes recent studies about the removal of EOCs using MOFs-related material.The synthesis strategies of both MOF particles and composites,including thin-film nanocomposite and mixed matrix membranes,are criticaily reviewed,as well as various characterization technologies.The application of the MOF-based composite membranes in adsorption,separation(nanofiltration and ultrafiltration),and catalytic degradation are discussed.Overall,literature survey shows that MOFs-based composite could play a crucial role in eliminating EOCs in the future.In particular,modified membranes that realize separation and degradation might be the most promising materials for such application.
