Highly selective methanol adsorption from dilute aqueous solutions using Mn 3 [Fe(CN) 6 ] 2 : a Prussian blue analog.

Mn 3 [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.
