In Situ Synthesis of MOF-76@Viscose Spunlace Nonwoven and the Adsorption Performance for Organic Dyes
To solve the difficulty of recovery and reuse of metal-organic frameworks (MOFs) in aqueous systems
MOF-76 was successfully immobilized onto viscose spunlace nonwoven (VSN) fibers
via
an
in situ
solvothermal synthesis. The resulting MOF-76@VSN was applied for the adsorption of organic dyes from water. The results showed that MOF-76 crystals with a rod-like morphology were anchored on the surface of VSN fibers
the average length was approximately 400 nm. MOF-76@VSN demonstrates high adsorption efficiency toward several anionic dyes
such as congo red (CR) and carmine (CAR). Under the optimal conditions of adsorption temperature of 35 ℃
and the adsorption solution of pH=7; the adsorption efficiency of MOF-76@VSN for CR was the maxmium
and reached 99.50% within 30 min. In addition
MOF-76@VSN exhibits good reusability
maintaining an adsorption efficiency of approximately 67.05% after five adsorption–desorption cycles.
