Ultrafast and selective adsorption of pharmaceuticals from wastewater by precisely designed metal organic framework with missing linker defects

Defect-enabling zirconium-based metal–organic frameworks for energy and environmental remediation applications

“…The as-prepared materials were proved to be highly efficient in removing these detected ones within 3 min (below the detection limits). 234 Another study showed that among various controls tested, a higher degree of structural damage within the framework of UiO-66 exhibited 320 mg g −1 of diclofenac sodium (DCF) adsorption capacity due to the presence of a high population of defective (active) sites. This value was much higher compared to perfect UiO-66 solid (54 mg g −1 ).…”

Defect-Rich Metal–Organic Framework Nanocrystals for Removal of Micropollutants from Water

“…These reports are still rare and do not cover a broad range of micropollutants. 47−49 Indeed, defective UiO-66 has been previously used as an adsorbent to eliminate the anticonvulsant carbamazepine, the antibiotic tetracycline hydrochloride, 29 the anti-inflammatory diclofenac sodium, 50,51 nonsteroidal anti-inflammatory pharmaceuticals such as ibuprofen, ketoprofen, naproxen, indomethacin, furosemide, salicylic acid, and acetophenone, 52,53 different nitrophenols (4nitrophenol, 2,4-dinitrophenol, and 2,4,6-trinitrophenol), 54 and the perfluorooctanesulfonate (PFOS). 55 In recent reports, the effect of controlled defects in MOF adsorbents has been investigated for toxic elements removal from water including mercury, 56 phosphates, 57 arsenic, 58 and selenite.…”

“…There are few studies that have examined the potential of UiO-66 in removing micropollutants by defect control or by functionalizing the MOF backbone. These reports are still rare and do not cover a broad range of micropollutants. − Indeed, defective UiO-66 has been previously used as an adsorbent to eliminate the anticonvulsant carbamazepine, the antibiotic tetracycline hydrochloride, the anti-inflammatory diclofenac sodium, , nonsteroidal anti-inflammatory pharmaceuticals such as ibuprofen, ketoprofen, naproxen, indomethacin, furosemide, salicylic acid, and acetophenone, , different nitrophenols (4-nitrophenol, 2,4-dinitrophenol, and 2,4,6-trinitrophenol), and the perfluorooctanesulfonate (PFOS) …”
