“…Membrane or nano-filtration can be costly to manufacture, energy-intensive, and require frequent filter replacement due to pore clogging, necessitating pressure for filtration [ 11 , 12 , 13 ]. Of these methods, adsorption is the most widely used industrially, with ongoing research into various dye adsorbents, including activated carbon [ 14 ], lignin-based products [ 15 , 16 , 17 ], chitosan [ 18 , 19 ], cellulose-based beads [ 20 ], Metal–Organic Framework (MOF) [ 21 , 22 , 23 , 24 ], and other thermopolymerized composites [ 25 , 26 ].…”

Vast amounts of dyeing wastewater released from the textile industry can not only cause water pollution but also have negative effects on the human body, such as skin irritation and respiratory diseases. Dye adsorption technology is necessary for the treatment of wastewater discharged from the dyeing industry and for environmental improvement. However, to remove dyeing wastewater, more energy and solvents are used to fabricate adsorbents, or excessive energy is used to filter dyeing wastewater out, resulting in more environmental pollution. Therefore, it is necessary to develop a method of filtering dyeing wastewater in a more environmentally friendly manner by minimizing the use of solvents and energy. In this study, we modified the surface of a textile substrate through UV irradiation to create a monomer capable of facilely bonding with dyes. Employing the UV photografting method, we were able to produce a dye adsorption filter in a more environmentally friendly manner, minimizing solvent usage and heat energy consumption required for absorbent synthesis. At a monomer concentration of 10%, the fabricated filter exhibited a dye removal efficiency of 97.34% after 24 h, all without the need for a pressure treatment or temperature increase. Moreover, it displayed an adsorption capacity of approximately 77.88 mg per 1 g of filter material.

“…MMMs based on polymer/MOFs are actively used for different membrane processes—pervaporation, ultrafiltration, gas separation and nanofiltration [ 41 , 42 , 46 , 47 , 48 ]. In recent years, nanofiltration MMMs based on polymer/MOFs were investigated for metal ion [ 42 , 46 , 49 ] and dye [ 49 , 50 , 51 , 52 ] removal from water. In the study [ 49 ], polyethersulfone (PES) membranes modified with various UiO-66-NH 2 content were tested in the nanofiltration of three dyes (Methylene Blue, Rhodamine B and Reactive Blue 21).…”

The membrane with 0.01 wt% UiO-66-NH 2 exhibited the best performance for the removal of dyes: rejection coefficient of 95.8% Methylene Blue, 94.2% Rhodamine B and 83.6% Reactive Blue 21.…”

Recently, there has been an active search for new modifiers to create hybrid polymeric materials for various applications, in particular, membrane technology. One of the topical modifiers is metal-organic frameworks (MOFs), which can significantly alter the characteristics of obtained mixed matrix membranes (MMMs). In this work, new holmium-based MOFs (Ho-MOFs) were synthesized for polyether block amide (PEBA) modification to develop novel MMMs with improved properties. The study of Ho-MOFs, polymers and membranes was carried out by methods of X-ray phase analysis, scanning electron and atomic force microscopies, Fourier transform infrared spectroscopy, low-temperature nitrogen adsorption, dynamic and kinematic viscosity, static and dynamic light scattering, gel permeation chromatography, thermogravimetric analysis and contact angle measurements. Synthesized Ho-MOFs had different X-ray structures, particle forms and sizes depending on the ligand used. To study the effect of Ho-MOF modifier on membrane transport properties, PEBA/Ho-MOFs membrane retention capacity was evaluated in vacuum fourth-stage filtration for dye removal (Congo Red, Fuchsin, Glycine thymol blue, Methylene blue, Eriochrome Black T). Modified membranes demonstrated improved flux and rejection coefficients for dyes containing amino groups: Congo Red, Fuchsin (PEBA/Ho-1,3,5-H3btc membrane possessed optimal properties: 81% and 68% rejection coefficients for Congo Red and Fuchsin filtration, respectively, and 0.7 L/(m2s) flux).
