Sustainable and Reusable Methylated Wood Waste Powder: An Eco-Friendly Solution for Efficient Removal of ۲-Methylisoborneol from Water

This study introduces a sustainable adsorbent derived from methylated wood waste for the efficient removal of ۲-methylisoborneol (۲-MIB), a pervasive taste and odor compound that compromises water quality and challenges treatment processes. Chemical modification via dimethyl sulfate-mediated methylation in alkaline aqueous-ethanol significantly enhanced hydrophobicity and adsorption performance. Gas Chromatography–Mass Spectrometry (GC–MS) analysis revealed ۹۵% ۲-MIB removal under optimized conditions (۰.۱۰ g dosage, ۱۰ min, pH ۷.۰). The adsorption followed a Langmuir isotherm (R² = ۰.۹۶۲), indicating monolayer adsorption on homogeneous sites with a ۹.۳۱ ng/g capacity. The adsorbent retained an efficiency of over ۹۰% after three regeneration cycles. Compared to commercial Powdered Activated Carbon (PAC), it reduces equilibrium time by ۵۰% and dosage requirements by ۴۰%, while cutting carbon emissions by ۳۰% through waste valorization. This work establishes methylated wood waste as an eco-friendly, high-performance solution for ۲-MIB mitigation in water treatment.
