Covalent organic frameworks (COFs) have a wide application prospect in wastewater treatment because of their unique structure and properties; however, the preparation pure COF membranes remains great challenge by reason insolubility unprocessability powders formed at high temperature pressure. In this study, continuous defect-free bacterial cellulose/covalent framework composite membrane was prepared using cellulose (BC) porphyrin-based with structures hydrogen bonding forces. The dye rejection rate toward methyl green congo red up to 99%, permeance about 195 L m-2 h-1 bar-1. It showed excellent stability under different pH conditions, long-time filtration, cyclic experimental conditions. addition, hydrophilicity surface negativity BC/COF made it certain antifouling performance, flux recovery can reach 93.72%. More importantly, exhibited antibacterial properties due doping COF, survival rates both Escherichia coli Staphylococcus aureus were less than 1% after exposure visible light. self-supporting synthesized strategy also has outstanding properties, addition separation effects, which greatly broaden materials water treatment.

The preparation of metal organic frameworks (MOFs) has come to the forefront in recent years because their outstanding physical and chemical properties. Many MOFs such as Zn, Co, Ni, Fe, Ag, etc., have been successfully synthesized. In this work, we followed solvothermal assisted route synthesize Ag-MOF (abbreviated AMOF) nanosheets then applied them a photocatalyst remove different pollutants, namely methyl orange (MO), crystal violet (CV), methylene blue (MB). Chemical composition, optical properties, morphology, microstructural analysis were analyzed using XPS, UV-visible spectrophotometer, FESEM, TEM, EDS, respectively. structural properties AMOF studied by X-ray diffraction (XRD). Nitrogen adsorption desorption isotherm utilized evaluate specific surface area pore size nanosheets. Further, showed notable photocatalytic performance for various dye pollutants degradation. results confirmed 74.5, 85.5, 90.7% MO, CV, MB removal after 120 min irradiation with rate constants (k) 0.0123, 0.0153, 0.0158 min−1, effect superoxide radicals (O2−) photogenerated holes (h+) on was investigated radical scavenger trapping studies. Moreover, stability study also recyclability photocatalyst. Therefore, findings research present realizable method grow successful degradation pollutants.

With the gradual increase of microplastics (MPs) in water and wastewater streams, it is imperative to investigate their removal using tertiary treatment systems minimize preferably prevent entrance into aquatic environments. Forward osmosis (FO) a non-pressurized membrane process with potential applications MPs from wastewater. However, efficient application FO relies on developing high-performance membranes low fouling tendency. are proven as emerging foulants systems, diminishing performance lifetime this highlights need consider MP sustainable membranes. The current study focuses novel modification thin film composite (TFC) by MIL-53(Fe) water-stable hydrophilic metal-organic framework. Experimental results demonstrated that optimized (0.2 wt% MIL-53(Fe)) achieved significantly higher flux (90% increase) 23% less reverse salt flux. modified also had decline experiments recovery after physical cleaning compared control affirming its antifouling efficiency. integration substrate proved be practical method for TFC improved properties against organic foulants.

Photocatalytic degradation under ultra-low powered light is a viable advanced oxidation process technique against extensive emerging contaminants. As new and remarkable class of nanoporous materials, metal-organic frameworks (MOFs), attract interest for the supreme adsorptive photocatalytic functionalities. An outstanding MOF, MIL-101(Fe) chosen as photocatalyst template synthesis α-Fe2O3 by simple thermal modification to improve structural properties toward methylene blue (MB) eradication. Octahedron-like (Modified MIL-101(Fe), M-MIL-101(Fe)) was superior in dispersion separation aqueous medium. Moreover, catalytic performance increased modified form ~ 7.3% 17.1% compared pristine respectively. Synergistic improvement MB removal achieved simultaneous adsorption/degradation 5-W LED irradiation. Parametric study indicated an 18.1% 44.5% observed increasing pH from 4 10, M-MIL-101(Fe) dose 0.2 1 g L-1, followed pseudo-second-order kinetics model efficiency dropped 38% concentration 5 20 mg L-1.
