Highly selective methanol adsorption from dilute aqueous solutions using Mn3[Fe(CN)6]2: a Prussian blue analog†
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.
