Recent Progress in the Removal of Heavy Metal Ions from Water Using Metal-Organic Frameworks

The efficient adsorption of heavy metal ions from wastewater has become a serious challenge from both environmental and biological viewpoints. Recently, porous metal-organic frameworks (MOFs), with metallic clusters and organic linkers, have been developed as promising structures in the capture of different toxic and hazardous substances, including heavy metal ions, because of their unique features. Here there is a collection for recent progress in the field of water remediation from the variable-valent metals in polluted water and the corresponding MOFs which are able to remove these pollutant agents from water. Meanwhile, effective factors in the absorption of metal ions are discussed. MOFs are considered to be a promising candidate for metal ions removal from wastewater.
