Analogize of metal-organic frameworks (MOFs) adsorbents functional sites for Hg2+ ions removal

Selective recognition of Hg2+ ions in aqueous solution by a CdII-based metal–organic framework with good stability and vacant coordination sites

“…S2a, ESI †). In addition, when the samples of JXUST-28 were soaked in aqueous solution with different pH values (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12), the positions of their PXRD peak remained consistent (Fig. 2b), whereas the framework collapsed when soaked in aqueous solutions with pH values of 1, 13 and 14 (Fig.…”

“…As the most important prevalent form of mercury pollution, Hg 2+ ions are mainly from the wastewater discharged by electronic equipment, and plastic and battery industries, which can lead to liver injury, cell dysfunction, endocrine disrupyion, and immune system damage. [1][2][3][4][5][6][7][8] The accumulation of Hg 2+ ions in tissues could give rise to several disorders, such as neuropathic disorders, cardiovascular disorders, acrodynia, digestive diseases, recognition memory impairments, hippocampal dysfunction, psychiatric disorders, chronic nephritis, minamata disease, and even death. 3,[9][10][11][12][13][14] Therefore, it is urgent to develop a Hg 2+ detection material with water stability.…”

Removal of metals from water using MOF-based composite adsorbents

“…100,101 Thus, MOF-based composites with processable form factors are therefore being developed to increase their utility by combining their properties with those of other functional materials, such as polymers, aerogels, graphene oxide and magnetic materials. 102–104…”

“…100,101 Thus, MOF-based composites with processable form factors are therefore being developed to increase their utility by combining their properties with those of other functional materials, such as polymers, aerogels, graphene oxide and magnetic materials. [102][103][104] Thanks to MOFs' diverse properties such as highly porous nature, chemical diversity, structural tailorability, low costs, and large-scale production, as well as properties of their composites with other functional materials such as morphological, mechanical, physicochemical, and functional properties, there are numerous opportunities for preparing MOF composite materials with outstanding performance in a variety of fields. 105,106 Moreover, MOF-based composites are capable of improving the adsorption performance of MOFs when compared with MOFs on their own, due to the synergy between different components.…”

Rational design of a functionalized metal–organic framework for ratiometric fluorimetric sensing of Hg2+ in environmental water

“…[1][2][3] Accumulation of even small quantities of Hg 2+ in humans via drinking water or the food chain can cause functional diseases, such as endocrine system disorders, renal failure, Hunter-Russell syndrome, Minamata disease, etc. 4,5 Considering the irreversible damage to human health caused by Hg 2+ , the maximum allowable level of Hg 2+ in drinking water is only 1 mg L −1 according to the US Environmental Protection Agency. Therefore, owing to the severely toxic characteristics of Hg 2+ , it is urgently needed to develop a highly sensitive, selective, and cost-effective sensing platform for Hg 2+ in environmental water.…”
