Abstract

Background

Synthetic dye removal from wastewater poses significant environmental challenges. Metal-organic Frameworks (MOFs), like ZIF-8, offer potential solutions due to their high adsorption capacities. This study has investigated the efficacy of a novel composite material, α-AlO@ZIF-8, for Methylene Blue (MB) removal.

Objective

This study aimed to assess the feasibility of α-AlO@ZIF-8 for MB removal. The synthesis microwave-assisted methods, physicochemical characterization, adsorption efficiency evaluation, and isothermal/kinetic modeling, has been conducted.

Methods

The α-AlO@ZIF-8 composite was synthesized and characterized using SEM, TEM, FTIR, and BET techniques. The adsorption efficiency for MB was tested, and isothermal/kinetic models were applied for mechanistic understanding.

Results

The composite exhibited robust crystal connections and uniform distribution, with particle sizes ranging from 0.5 to 0.6 µm. MB adsorption efficiency exceeded 97.8% under optimal conditions. Isothermal and kinetic modeling revealed favorable adsorption behavior, notably with the Langmuir and pseudo-second-order models.

Conclusion

Microwave-synthesized α-AlO@ZIF-8 shows promise for efficient MB removal, with treatment efficiencies surpassing 97%. This underscores the potential of MOFs in wastewater treatment and emphasizes the importance of understanding adsorption mechanisms for optimization.
