Encapsulation of tungstophosphoric acid into harmless MIL-101(Fe) for effectively removing cationic dye from aqueous solution

Abstract

H₃PW₁₂O₄₀ was incorporated into cages of harmless MIL-101(Fe). The composite material exhibited excellent adsorption performance for the cationic dyes MB and RhB, can be utilized in the selective capture and separation of organic dyes in water and is reusable and stable.
