Özet
In this study, we report synthesis of new fluorescent compound integrated with Fe3O4 nanoparticles for the detection of mercury ion (Hg2+) in aqueous environment. Fluorescent compound synthesized by reacting dansyl chloride with isonipecotic acid in one simple step reaction. The synthesized compound, dansyl-isonipecotic acid (DIA) was coated on Fe3O4 nanoparticles. Fe3O4-DIA nanoparticles have average size of 20 nm and pore size 0.3 nm as confirmed from Transmission Electron Microscope (TEM). Fluorescence study shows the quenching in intensity after addition of Hg2+ ion in Fe3O4-DIA nanoparticles solution, which is due to energy transfer from excited state of ligand to low-lying empty d-orbital of Hg2+. The quenching effect was also confirmed from confocal microscope images of Fe3O4-DIA nanoparticles. © 2020 Elsevier B.V.
