Lignin-Modified Metal–Organic Frameworks for Fluorescence Detection of Cr6+ and Adsorption of Congo Red

“…UV–visible spectroscopy was employed to investigate the mechanism of the fluorescence burst and fluorescence enhancement. As shown in Figure c, Comparing the absorption spectra of Cr 6+ with the excitation spectrum of MIL-NL, the absorption spectra of Cr 6+ overlaps with the excitation spectra of MIL-NL, there is not only a red shift but also a large absorbance enhancement . The results suggest that the formation of the internal filtration effect is due to the absorption of the emission light of MIL-NL by Cr 6+ .…”
