tailieunhanh - Novel triazine-based colorimetric and fluorescent sensor for highly selective detection of Al3+

The complexation activity of NADO with various metal ions in an ethanolic solution is specifically studied by means of fluorescent spectra. The NADO exhibits a significant fluorescence enhancement at 469 nm in presence of Al3 þ due to the formation of a complex. | Journal of Science Advanced Materials and Devices 4 2019 237e244 Contents lists available at ScienceDirect Journal of Science Advanced Materials and Devices journal homepage locate jsamd Original Article Novel triazine-based colorimetric and fluorescent sensor for highly selective detection of Al3þ J.

The complexation activity of NADO with various 26 April 2019 metal ions in an ethanolic solution is specifically studied by means of fluorescent spectra. The NADO Accepted 8 May 2019 Available online 16 May 2019 exhibits a significant fluorescence enhancement at 469 nm in presence of Al3þ due to the formation of a complex. Under an optimized condition the detection limit is found to be mM. As the concentration of Al3þ is increased the fluorescence intensity gradually increases due to the formation of the complex. Keywords Fluorescent sensor The 1 1 binding stoichiometry between Al3þ and NADO is confirmed by the Job s plot and the HR-LCMS Colorimetric mass spectrum of the metal complex.
