Abstract

Mn₃[Fe(CN)₆]₂ (MnHCF) selectively adsorbs methanol from water with a distribution coefficient of 11 mL g⁻¹, which is 3–11 times that of activated carbons and zeolites. MnHCF exhibits an adsorption capacity of 0.36 mmol g⁻¹ and can adsorb 1000 mg MeOH per L in aqueous solution, demonstrating its effectiveness for treating methanol-contaminated wastewater.
