TL;DR
A new magnetic carbon nanohybrid was developed to efficiently and sustainably remove methyl blue dye from water.
Contribution
A novel magnetic nanohybrid using Eucalyptus extract was developed for fast and reusable methyl blue removal.
Findings
The nanohybrid achieved a maximum adsorption capacity of 92.9 mg g−1 for methyl blue.
The material retained over 98% removal efficiency after five regeneration cycles.
The system successfully removed over 91% of methyl blue from synthetic effluents.
Abstract
The contamination of aquatic systems by industrial dyes, particularly methylene blue (MB), presents a significant environmental challenge due to their chemical stability and toxicity. In this study, the development and application of a novel magnetic nanohybrid comprising multiwall carbon nanotubes (MWCNTs) functionalized with maghemite (γ-Fe2O3) nanoparticles biosynthesized using Eucalyptus globulus extract (denoted MWNT-NPE) is reported. The material was thoroughly characterized by X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET), Vibrating Sample Magnetometer (VSM), and Fourier-Transform Infrared (FTIR) techniques, revealing high crystallinity, mesoporosity, and superparamagnetic behavior. The MWNT-NPE exhibited exceptional MB adsorption performance under optimized conditions (pH 6, 0.8 g L−1 dose, 40 min equilibrium), achieving a maximum adsorption capacity of 92.9 mg g−1.…
