Highly Efficient AF@MOF-808 for the Selective Detection of-Fe3+Ions and Cr2O72-Anions from Aqueous Solution
AF@MOF-808 incorporating the acriflavine(AF)dye into the nanocages of MOF-808 was constructed by one-pot hydrothermal method,whose crystallization,morphology and stability were characterized by the X-ray powder diffractometer(XRD),scanning electron microscope(SEM)and thermogravimetric analysis(TGA).AF@MOF-808 exhibits bright green light emission with the high quantum yield of 38.27%and can selectively detect Fe3+ion and Cr2O72-anion from 12 kinds of metal ions or anions in the aqueous solution.
