Synthesis and characterization of ZIF-8-based PVDF mixed matrix membranes and application to treat pulp and paper industry wastewater using a membrane bioreactor

Abstract

The metal organic framework (MOF) of zinc imidazolate framework-8 (ZIF-8) is synthesized by solvothermal method and added into polyvinylidene fluoride (PVDF) membrane to study the pollutant removal performance using the...

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

“…28 The h-BN/PEI surface has a lower S a value than the ZIF-8 and MoS 2 functionalized PEI mixed matrix membranes because of the alteration in the interaction of polymer chains in the presence of h-BN. 27…”

“…The number of finger-like pores in the prepared mixed matrix membranes is more uniform and has effectively developed in the membrane structure. 27 In the MOF and 2D nanomaterial functionalized PEI mixed matrix membranes, a sponge-like structure is observed due to the transition zone and a large number of finger-like channels. These modifications could be attributed to the increased exchange rate of solvent and non-solvent in the presence of nanoparticles.…”

A metal organic framework decorated 2-dimensional nanomaterial based nanocomposite photocatalyst for photocatalytic degradation of dyes from textile industry wastewater

“…In the first step, the PVDF dope solution of 18 wt% is prepared to fabricate the mixed matrix membranes as per our previous study. 6 In the second step, the synthesized MIL-101(Cr) MOF, h-BN and TiO 2 functionalized MIL-101(Cr) composites are added to the NMP using an ultrasonication bath (45 kHz, 150 W). Further, to obtain a homogeneous dispersion of each photocatalyst in the PVDF dope solution, 1.5 mL of Tween-80 is added.…”

“…In this technique, microfiltration membranes and ultrafiltration membranes are used in conjunction with biological treatment for secondary wastewater treatment. 6 There are different types of dyes such as anionic, cationic, and reactive dyes used in industries and a huge quantity of dye-contaminated wastewater is generated and without further treatment, it is passed into water bodies. There are several industrial dyes released into the environment from two major sources, viz., (i) textile industries and (ii) effluents from dyes synthesis plants.…”

Preparation of Poly(acrylic acid‐co‐acrylamide) Hydrogel‐Modified PVDF Membrane and Its Separation and Antibacterial Properties

“…[12] Membrane separation technology has the characteristics of high efficiency, energy saving, environmental protection, and molecular filtration, since filtration process is simple and easy to control. [13] Therefore, it has been widely used in food industry, [14] pharmaceutical industry, [15] petrochemical industry, [16] paper industry, [17] dyeing and finishing industry, [18] water treatment industry, [19] and other fields, [20][21][22] which has produced great economic and social benefits and becomes one of the most important methods in separation science.…”
