Synthesis, characterization, and application of ZIF-8/Ag3PO4, MoS2/Ag3PO4, and h-BN/Ag3PO4 based photocatalytic nanocomposite polyvinylidene fluoride mixed matrix membranes for effective removal of drimaren orange P2R

Antibiotic removal by metal–organic framework and 2D nanomaterial based polyetherimide mixed matrix membranes using a membrane bioreactor

“…24,25 The bands detected at 1313 cm −1 and 744 cm −1 correspond to C–N stretching and imide group bending. 23 Similarly, the red color spectra of the ZIF-8 functional PEI membrane represent the different functional groups. The aromatic C–H stretch band of imidazole is observed at the peak at 1590 cm −1 .…”

“…A strong peak is observed at 815 cm −1 in the h-BN functional PEI membrane, which is consistent with out-of-plane B–N–B bending vibration, suggesting the honeycomb structure of h-BN. 10,23…”

“…ZIF-8 is synthesized using the method described in our previous study. 23 The ZIF-8 nanoparticles are made up of 2.205 g Zn (NO 3 ) 2 ·6H 2 O and 2.435 g 2-MeIm in 300 mL methanol. These solutions mix effectively at room temperature.…”

Challenges surrounding nanosheets and their application to solar-driven photocatalytic water treatment

“…PMRs in this case refer to those which immobilise PC with a membrane in order to increase the mass transfer over the immobilised photocatalyst. This can be by inclusion in the membrane dope to form mixed matrix membranes (MMM), 218,219 on a membrane surface, [220][221][222][223] or the membrane can be fabricated directly from PC material 56,224,225 (less common). This is important to note as suspended photocatalytic slurry reactors with a membrane based PC recovery stage are sometimes dubbed slurry-PMRs.…”

Domestic wastewater treatment by membrane bioreactor system and optimization using response surface methodology

“…The disadvantages are the slower growth rate of microorganisms, require pretreatment, fouling tendency, and capital cost (Cartagena et al 2013;Cantinho et al 2016;Sonawane and Murthy 2020). MBR treatment can be used to treat a variety of wastewaters, including domestic, chemical industry wastewater, food industry wastewater, and pharmaceutical industry wastewater (Moya-Llamas et al 2018;Battistelli et al 2019;Sonawane and Murthy 2022), etc. Human excrement and greywater constitute the majority of the wastewater discharged after domestic use.…”
