ZIF‐8 Composites for the Removal of Wastewater Pollutants

ChemistrySelect, Journal Year: 2024, Volume and Issue: 9(24)

Published: June 24, 2024

Abstract The presence of dyes in wastewater poses a significant environmental challenge due to their permanence toxicity and potential harm ecosystems. Because high porosity adjustable characteristics, metal‐organic frameworks (MOFs) have become attractive materials for effective dye removal. Among various MOFs, zeolitic imidazolate (ZIFs) garnered attention, especially ZIF‐8, its excellent stability, porosity, pore size remarkable adsorption capacity. This review article provides comprehensive overview recent advances the implementation ZIF‐8 composites removal pollutants from wastewater. synthesis methods, structural characteristics performance are discussed. Furthermore, impact different factors such as pH, temperature, concentration, contact time etc. were also highlighted. Moreover, detailed mechanism was Finally, current challenges future perspectives production based on presented.

The pervasive presence of toluene in aquatic environments, primarily due to oil spills and industrial effluents, necessitates the development effective sustainable remediation strategies. This study introduces ZIF-8@DES-treated loofah sponge (ZIF-8@DLS), a novel adsorbent composite material, synthesized via an situ process that integrates high surface area ZIF-8 with natural sponge. was characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), confirming successful loading onto substrate. adsorption capacity ZIF-8@DLS for evaluated, achieving maximum 145.3 mg/g efficiency 72% under standard conditions. Kinetic studies revealed predominantly followed pseudo-second-order model, indicative chemisorption. isotherm data were found align more closely Freundlich suggesting multilayer mechanism on composite's heterogeneous surface. demonstrates promising synergy performance, cost-effectiveness, facile synthesis, environmental benignity, positioning it as candidate practical applications wastewater treatment adsorptive separation processes.

Green Fabrication of Zinc-Based Metal–Organic Frameworks@Bacterial Cellulose Aerogels via In Situ Mineralization for Wastewater Treatment

Molecules, Journal Year: 2025, Volume and Issue: 30(5), P. 982 - 982

Published: Feb. 20, 2025

Compared to conventional adsorbents, zinc-based metal-organic frameworks (MOFs) such as zeolite imidazolium skeleton-8 (ZIF-8) exhibit enhanced thermal, chemical, and structural stability. Nonetheless, their powdered form results in limited dispersibility aqueous solutions a tendency aggregate, which significantly restricts utility adsorption applications. This study reports green composite aerogel through the situ mineralization of ZIF-8 onto bacterial cellulose (BC) for effective removal toxic metal ions (Cu2+) Congo red (CR) from wastewater. The ZIF@BC was characterized using scanning electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, X-ray diffraction, photoelectron specific surface area analysis. findings indicated that produced were evenly distributed across BC nanonetwork, facilitating CR Cu2+. maximum capacities aerogels determined be 397.55 mg/g 424.80 Cu2+, per Langmuir isotherm. Furthermore, ZIF-8@BC demonstrated excellent selectivity reusability, particularly adsorption. proposed mechanism interaction between Cu2+ involves electrostatic interactions, hydrogen bonding, π-π coordination ion exchange, microchemical precipitation, pore diffusion. research offers significant promise utilization MOF powders highlights substantial industrial potential.
