“…Figure 1 shows the XRD patterns of MIL-101 and AgNO 3 -loaded adsorbents. The diffraction peaks of pure MIL-101 are in good agreement with those reported patterns, 43,44 indicating that MIL-101 is well synthesized. After AgNO 3 loading, all the samples preserve the featured patterns as MIL-101, illustrating the structural integrity of the support.…”

Effective utilization of Ag(I) π-complexation adsorbents for practical C 2 H 4 /C 2 H 6 separation urges both good separating performances and high stabilities. In this work, we incorporated AgNO 3 onto a typical metal− organic framework (MOF) of MIL-101 to obtain efficient Ag(I) πcomplexation adsorbents. It was found that the separation performances were highly dependent on the location of the AgNO 3 , which could be at the interior or the exterior of nanoporous MIL-101. Confining AgNO 3 inside the nanopores of MIL-101 was achieved through employing a double-solvent approach. The resulting AgM-DS adsorbents exhibited superior performances compared with not only pristine MIL-101 but also other modified samples with AgNO 3 at the exterior of MIL-101. To be specific, the optimal 1.6AgM-DS adsorbent secured good C 2 H 4 /C 2 H 6 separation, which is C 2 H 4 uptake (75.5 cm 3 •g −1 ) and C 2 H 4 /C 2 H 6 selectivity (9.5) at 100 kPa. For comparison, the C 2 H 4 uptakes for MIL-101, 1.6AgM-WI, and 1.6AgM-SG were merely 48.1, 56.0, and 19.4 cm 3 •g −1 , and the corresponding IAST selectivity was only 1.1, 8.1, and 1.8, respectively. It was further indicated that the 1.6AgM-DS adsorbent maintained good stability for 3 weeks, alleviating the light sensitivity of AgNO 3 . This work opens an avenue for constructing stable Ag(I) sites on MOFs to develop π-complexation adsorbents.

“…The MIL-101(Cr) photocatalyst is synthesized using the thermal process according to existing studies with some modifications. 19 Initially, chromium nitrate and terephthalic acid are added to 20 mL of water at around 2.00 g and 0.83 g, respectively, and the mixture is stirred at room temperature for 35 min. In the second step, the mixed solution is transferred into a Teflon lined stainless steel autoclave.…”

“…This herbicide has been forbidden in many European countries since 1992 because of its toxicity, and the limit imposed by the Council Directive 98/83/EC for its concentration in water is 0.1 µg/L. Moeini et al [114] tested titanium dioxide encapsulated in salicylaldehyde-NH 2 -MIL-101 (TS-MIL) to remove atrazine. Starting from an aqueous solution with a pollutant concentration of 30 mg/L, 90% of it was removed using 2 g/L of TS-MIL within 30 min.…”

Water Purification of Classical and Emerging Organic Pollutants: An Extensive Review

2021

View full text Add to dashboard Cite

The main techniques used for organic pollutant removal from water are adsorption, reductive and oxidative processes, phytoremediation, bioremediation, separation by membranes and liquid–liquid extraction. In this review, strengths and weaknesses of the different purification techniques are discussed, with particular attention to the newest results published in the scientific literature. This study highlighted that adsorption is the most frequently used method for water purification, since it can balance high organic pollutants removal efficiency, it has the possibility to treat a large quantity of water in semi-continuous way and has acceptable costs.
