Abstract:Inorganic mercury (Hg 2+ ) produces toxic effects even at very low concentration. High sensitive fluorescent probes for Hg 2+ detection has been researched and synthesized. A fluorescence detection system is built for Hg 2+ detection in water environment with fluorescent probes as the detection reagent. Fiber coupled LED with high brightness is developed and used as excitation light source. And the optimized excitation wavelength is about 520 nm. The measurements of fluorescence spectra is obtained by means of… Show more
