Synthesis of aqueous media stable MIL101-OH/chitosan for diphenhydramine and metronidazole adsorption

Quick removal of metronidazole from aqueous solutions using metal–organic frameworks

“…The removal of contaminants using MOFs usually permits facile adsorbent regeneration due to their high stability in aqueous medium. 36,37 There are various reports concerning removal of antibiotics using MOFs. 38 Peng et al developed porous MIL-53(Al) with a flexible structure for efficient removal of dimetridazole at its distinct concentrations.…”

Anchoring HPW by amino‐modified MIL‐101(Cr) to improve the properties of SPEEK in proton exchange membranes

“…where V and M are the consumed volume and quality score of NaOH aqueous, and W dry is the weight of dry membrane. 42,43 These images indicated the framework of the MIL-101(Cr) after the post-synthetic modification process, and no significant changes were observed in the morphology of aminomodified MOFs.…”

“…MIL-101(Cr) was synthesized by the hydrothermal method according to the previously reported procedures. 42,43 The mixture solution of 0.664 g H 2 BDC, 1.6 g Cr(NO 3 ) 3 Á9H 2 O and 0.2 mL HF with 28 mL water as solvent was decanted into a Teflon-lined autoclave at 220 C for 8 h. Through repeating centrifugation, washing by DMF and ethanol at 70 C for 5 h and final vacuum drying, MIL-101(Cr) was successfully prepared.…”

“…5 In this manuscript, MIL-101(Cr)-NH 2 was synthesized by hydrothermal method, and was then used to anchor HPW in SPEEK composite membranes. 42,43 The resulting PEM exhibited enhanced acid retention capacity and robust dimensional stability. It is worth noting that the strong hydrogen bond [30][31][32][33][34] between HPW and amino group of MIL-101(Cr)-NH 2 constructed a proton conductivity path to facilitate proton transfer, which brought a new idea to design the potential candidate for fuel cells.…”
