Polluted water has become a concern for the scientific community as it causes many severe threats to living beings. Detection or removal of contaminants present in wastewater and attaining purity that can be used various purposes are primary responsibility. Different treatment methods have already been purification sewage. There is need low-cost, highly selective, reusable materials efficiently remove pollutants purify contaminated water. In this regard, MOFs shown significant potential applications such supercapacitors, drug delivery, gas storage, pollutant adsorption, etc. The outstanding structural diversity, substantial surface areas, adjustable pore sizes make them superior candidates treatment. This Review provides an overview interaction science engineering (kinetic thermodynamic aspects with interactions) underpinning purification. First, fundamental strategies synthesis MOFs, different categories, their applicability summarized, followed by detailed explanation mechanisms. Finally, current challenges future outlooks research on MOF toward adsorption hazardous components discussed. A new avenue modifying characteristics separation materials, which will undoubtedly direct work, also summarized.

Nuclear power is increasingly viewed as a solution to growing global energy demand and challenges posed by climate change. Large-scale extraction of uranium from seawater considered crucial for sustainable nuclear generation. This paper presents the room temperature synthesis UiO-66-NH2 (Ce) MOF its subsequent postsynthetic modification phosphorus-functionalized UiO-66-NHPOPh2 efficient materials capture. The MOFs were thoroughly characterized FT-IR spectroscopy, pXRD, TGA, SEM, BET surface area analysis. influence pH contact time on uptake was systematically investigated. pH-dependent adsorption studies revealed over 95 99% sorption (Ce), respectively, in range 3–9, with maximum observed at 5, mirroring most naturally occurring water bodies. Interestingly, phosphinic-amide-functionalized exhibited higher capacity across wide compared amine functionalized MOF. Uranium kinetics suggests significant (more than 95%) these within 1 min interaction. Moreover, MOF, estimated mg U/g sorbent using Langmuir isotherm model, surpassed that many other reported sorbents. Adsorption conducted tap water, drinking demonstrated real samples. Importantly, be selective presence common competing ions. Desorption various reagents indicated material's potential reuse. Additionally, EXAFS uranium-sorbed samples suggest both lead coordination uranyl(VI) ions, thereby providing mechanism their
