Abstract
A novel Cd-MOF was synthesized and used as a fluorescence sensor for rapid,simple,and reliable fluorescence recognition and detection of nitroimidazole antibiotics in water.Fluorescence spectra investigation have shown that the complex exhibits high selectivity and sensitivity,excellent response ability,and low detection limit towards metronidazole(ODZ),metronidazole(DTZ),and metronidazole(MDZ)(2.66×10-3μmol/L,1.465×10-3μmol/L,2.66×10-3μmol/L for ODZ,DTZ and MDZ,separately).The sensing mechanism of Cd-MOF was analyzed by UV absorption spectroscopy,and the experimental results showed that the fluorescence quenching of Cd-MOF by nitroimidazole antibiotics was attributed to the fluorescence internal filtration effect.The synthesized Cd-MOF has broad development prospects and is expected to achieve practical detection of nitroimidazole antibiotics in water.
