“…The stability of UiO‐66‐NH 2 , Br@UiO‐66‐NH 2 , and MIP@UiO‐66‐NH 2 was tested by X‐ray diffractometer and TGA. As shown in Supporting Information A, all the diffraction peaks of UiO‐66‐NH 2 (2θ = 7.42, 8.59, and 25.77°) coincided with a previous report . Compared with the three diffraction peaks for UiO‐66‐NH 2 , the intensity of these peaks rarely changed for Br@UiO‐66‐NH 2 and MIP@UiO‐66‐NH 2 .…”

In this work, a novel surface molecularly imprinted polymer with high adsorption capacity, high adsorption rate, and high selectivity for fluoroquinolones was prepared on the surface of UiO‐66‐NH2, which is a kind of metal‐organic framework. The surface morphology and adsorption properties of this molecularly imprinted polymer were investigated. The maximum adsorption capacity was 99.19 mg/g, and adsorption equilibrium was achieved within 65 s. Combined with reversed‐phase high‐performance liquid chromatography, the molecularly imprinted polymer was used to selectively enrich, separate and analyze fluoroquinolones present in lake water. The results showed that the recoveries of the four fluoroquinolones were 92.6–100.5%, and the relative standard deviations were 2.9–6.4% (n = 3). The novel molecularly imprinted polymer is an excellent adsorbent and has broad application prospects in the enrichment and separation of trace analytes in complex samples.

“…The results of this study indicate that the functional group is not so important in the adsorption, but the presence of a free and available sulfur atom for interaction with Hg II is very effective in the adsorption process. Similar results were obtained for the adsorption of Pb II by the structures …”

“…As previously mentioned, the combination of high porosity with well‐distributed functionalities is essential for the complete treatment of water from pollutants such as Pb II and Hg II . As shown in Table , high Hg II adsorption capacities of 900, 769 and 714 mg g −1 were obtained for BioMOF, UiO‐66‐NHC(S)NHMe and thiol‐HKUST‐1, respectively. These values are well comparable to the results obtained from materials such as functional thiol mesoporous silica (635 mg g −1 ) and modified covalent organic frameworks (COFs; 734 mg g −1 for TAPB‐BMTTPA‐COF336) .…”

Metal-organic frameworks (MOFs), which are inorganic-organic hybrid porous materials prepared from metal ion/clusters and multidentate organic ligands, have evolved to be next-generation utility materials because of their usability in diverse applications. These porous materials, with excellent chemical stability and a wide variety of functional groups, have demonstrated their utility to the area of capturing various types of hazardous metal ion pollutants. This conceptual review focuses on recent progress in reported MOFs as Hg and Pb adsorbents emphasizing the general concepts that have guided important developments in these area and their implications for future research. Also, we suggest our personal insights into future research opportunities in the area and we hope to encourage more researchers to engage in this new field of MOF-based materials with the goal of environmental pollution management.

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.
