Nanocellulose-Based Materials for Water Pollutant Removal: A Review

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(15), P. 8529 - 8529

Published: Aug. 5, 2024

Cellulose in the nano regime, defined as nanocellulose, has been intensively used for water treatment. Nanocellulose can be produced various forms, including colloidal, redispersible powders, films, membranes, papers, hydrogels/aerogels, and three-dimensional (3D) objects. They were reported removal of contaminants, e.g., heavy metals, dyes, drugs, pesticides, pharmaceuticals, microbial cells, other pollutants from systems. This review summarized recent technologies treatment using nanocellulose-based materials. A scientometric analysis topic was also included. Cellulose-based materials enable salts offer advanced desalination. are widely substrates, adsorbents, catalysts. applied pollutant via several methods such adsorption, filtration, disinfection, coagulation/flocculation, chemical precipitation, sedimentation, filtration (e.g., ultrafiltration (UF), nanofiltration (NF)), electrofiltration (electrodialysis), ion-exchange, chelation, catalysis, photocatalysis. Processing cellulose into commercial products enables wide use adsorbents

Simultaneous removal of cationic and anionic dyes by highly efficient and recyclable ZIF‐67/expanded vermiculite (ZIF‐67/EV) composites

Water Environment Research, Journal Year: 2025, Volume and Issue: 97(2)

Published: Feb. 1, 2025

This study focuses on the synthesis of composite materials using Zeolitic imidazolate frameworks (ZIF-67) nanoparticles as an effective adsorbent, along with different concentrations (2-10%) thermally expanded vermiculite (EV) a low-cost and natural adsorbent substrate. The pristine their composites were fully characterized XRD, FTIR, BET, SEM, zeta potential, EDS techniques. pseudo-second-order kinetic model described both organic dyes' adsorption synthesized adsorbents. Accordingly, calculated capacities Congo Red (CR) Malachite Green (MG) dyes over adsorbents found to be about 22.72 49.02 mg/g for pure EV, 100 ZIF-67, 90.91 ZIF-67/EV-2, ZIF-67/EV-5, 95.24 99.01 ZIF-67/EV-7, 92.59 97.09 ZIF-67/EV-10, respectively. Langmuir isotherm fits experimental data best in studied temperature range (298-313 K). Among materials, ZIF-67/EV-5 (containing 5% EV flakes) showed highest maximum 1428.6 1114.2 MG CR at pH 7 298 K. Moreover, it removal efficiency (up 99.5%) toward cationic anionic binary mixture dyes. Finally, regeneration recyclability this 12% decrease dye after five cycles. ZIF-67/EV may therefore used efficient inexpensive simultaneous from contaminated water. PRACTITIONER POINTS: ZIF-67/expanded simultaneously remove wastewater. Kinetics, isotherms, thermodynamics showing good achieved dyes, Various interactions like π-π stacking coordination are proposed mechanisms adsorption. selectivity separating maintained high even 5 reuse

Metal–Organic Frameworks (MOFs) for Adsorption and Degradation of Microplastics

Microplastics, Journal Year: 2025, Volume and Issue: 4(1), P. 11 - 11

Published: March 1, 2025

Microplastics (MPs) are currently a serious environmental problem, primarily due to their persistence in the environment, low concentration, and difficulty detection disposal. MPs have also been detected humans shown be harmful. Although there methodologies for recovery or elimination most water treatment plants, significant portion still bypasses these systems. It is this percentage that we must try eliminate. In addition finding new of MPs, it important find materials adapted process. context, metal–organic frameworks (MOFs) high-versatility compounds can synthesized using different techniques obtain with properties, such as porosity, morphology, conductivity, etc. These adsorb ways, electrostatic interaction, bond formation, etc., they obtained by containing metals catalyze reactions formation highly reactive species oxidize MPs. This review examines how MOF gained attention adsorption-based removal discusses problems associated possible solutions.
