Role of metal-organic framework composites in removal of inorganic toxic contaminants

Metal-sulfide/polysulfide functionalized layered double hydroxides – recent progress in the removal of heavy metal ions and oxoanionic species from aqueous solutions

“…Chemical separations allow trace-level removal of heavy metal ions besides achieving superior selectivity and faster kinetics. Among these, adsorption, ion exchange, and (reductive) precipitation mechanisms have garnered widespread attention across a diverse array of materials, including activated 21–23 and sulfur-impregnated carbon, 24–26 zeolites, 27–29 metal–organic frameworks, 30–32 layered metal-sulfides, 33 clay minerals, 34–36 various organic molecules, 37–39 and organic–inorganic composite materials. 40–43…”

Analysis of Radioactive Iodine Trapping Mechanism by Zinc-Based Metal–Organic Frameworks with Various N-Containing Carboxylate Ligands

“…Metal–organic frameworks (MOFs) have various applications such as gas storage, separation, and catalysis. − In the past time, various MOFs had been used to study iodine capture, , such as Cu-BTC, MIL-53 series (Al), MIL-101 (Al), MOF-74, JNU-200 (Co), Zr-MOFs, ZIF-8, and Cd-MOF . Further research was needed to explore MOFs with higher adsorption capacity, selectivity, stability, and low cost.…”

A review of metal–organic framework (MOF) materials as an effective photocatalyst for degradation of organic pollutants

“…8 Inorganic pollutants encompass a range of cations, oxo-anions, and heavy metal ions, including radioactive elements, which are of utmost ecological concern. 9,10 On the other hand, organic pollutants constitute a diverse group that includes pharmaceuticals and personal care products (PPCPs), dyes, oils, polyaromatic hydrocarbons, detergents, pesticides, insecticides, and herbicides. 11,12 Although their concentrations may not be as high as those of their inorganic counterparts, organic pollutants are particularly concerning due to their high stability and long-term environmental impact.…”
