Highly Porous MOFs: A New Progress in Hazardous Metal Ion Pollutants Treatment
count: [2018-03-29]

Recent research by Institute of Plasma Physics, Chinese Academy Sciences (ASIPP) and North China Electric Power University (NCEPU) found that highly porous metal–organic frameworks (MOFs), with excellent chemical stability and abundant functional groups represent a new addition to the area of capturing various types of hazardous metal ion pollutants. 

Nuclear energy is currently undergoing rapid development and attracting broad research effort with the increase in energy demand. In the meanwhile, large amounts of radioactive waste are  released into the environment due to the nuclear fuel cycle and mining operations, which causes a long-term threat to the surface and subsurface environments. Radioactive metal ions can cause progressive and irreversible damage to cells, lymph nodes, lungs, livers, pancreases, and bones because of its high toxicity and radioactivity even at low concentration. So, highly efficient removal of metal ion pollutants remains a vital task from the biological and environmental standpoint because of their harmful effects on human health and the environment. 

Scientists have been seeking for effective materials to capture the toxic and radioactive metal ions to avoid the danger to human. Over the years, the research groups led by Associate Professor Changlun Chen from Institute of Plasma Physics, Chinese Academy Sciences (ASIPP), and Professor Xiangke Wang from North China Electric Power University have made important contributions to the related field of nanomaterials and MOFs for enrichment of radioactive elements. 

Their achievements are published as a review article in the Chemical Society Reviews, titled ‘Metal-organic framework-based materials: superior adsorbents for the capture of toxic and radioactive metal ions’. Chemical Society Reviews is the core top journal of Royal Society of Chemistry for the review article (Impact Factor (2017): 38.618). This review summarized recent process in the application of MOFs for the capture of toxic and radioactive metal ions, and proposed insights into future research opportunities and challenges in the hope of stimulating more researchers to engage in this new field of MOF-based materials for environmental pollution management.
