Recently, the Quality and Safety Research Group of the Institute of Vegetables and Flowers of the Chinese Academy of Agricultural Sciences has made new progress in the analysis and application of metal ions in MOFs/nanocomposite membranes. The relevant research results are”Recent advances in metal-organic frameworks/membranes for adsorption and removal of metal ions” was published on TrAC Trends in Analytical Chemistry (IF= 9.801, DOI:10.1016/j.trac.2021.116226).
Metal ions are widely found in nature. On the one hand, they are trace elements necessary for the human body; on the other hand, they are heavy metal ions that cause environmental pollution and endanger human health. Therefore, it is of great significance to analyze, detect, enrich and adsorb metal ions in the environment and food. Metal-organic frameworks (MOFs) are a type of crystalline porous material with a periodic network structure. It is formed by bridging organic ligands formed by self-assembly of inorganic metal-containing nodes. It has a high specific surface area, tunable micropores, and low The characteristics of skeleton density, etc., are widely used in the fields of ion adsorption, drug delivery, gas storage and chemical separation. However, most studies only emphasize the structure design and modification strategy of MOFs-derived nanostructures as high-performance adsorbents for environmental remediation, and lack of systematic summary and analysis of MOFs and their nanocomposite membrane materials in the metal ion removal mechanism and application. .
In response to the above problems, this research system summarizes the relative synthesis methods and modification strategies of MOFs and MOFs/nanocomposite membranes, and focuses on the latest developments in the application of MOFs nanocomposites in the enrichment and adsorption of different types of metal ions and analysis and detection applications , Discussed the technical problems to be solved and the future development trend of MOFs materials. This research provides an important theoretical basis for in-depth understanding of the rational design and application research of MOFs with different morphological structures, and to promote the development of MOFs nanocomposite membrane materials.
