摘要: Nitrogen-doped carbon quantum dots (CDs) were synthesized in ethanol media by using citric acid (CA) as the source and ethanediamine (EDA) nitrogen source. The obtained CDs characterized multiple analytical techniques including high resolution transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) Fourier transform infrared (FTIR). prepared can be constructed a fluorescent probe for detection of Hg2+ with good sensitivity selectivity. Upon addition I−, fluorescence restored due to strong interaction between I−. also Br− changing buffer solution. linear ranges limits 0–20 μM 65 nM 0–28 98 Br−, respectively. In addition, UV-vis spectrum this sensing system was studied validate mechanism Hg2+, I− Br−.
