Water Safety for Human Health: Detection of Pollutants by Blue-Emission Carbon Quantum Dots via Three Modes in Different Polluted Water Bodies

Water quality directly affects human health. It is very important to design a probe that can detect the pollutants in water. In this study, we synthesized one kind of carbon dots (CDs), which could emit strong blue fluorescence. The fluorescence be quenched by 2,4,6-trinitrophenol (TNP) ascribed energy transfer (ET), lemon yellow (LY) inner filter effect (IFE), and HClO surface passivation (SP). TNP, LY, are common contaminants By our experiment, it was proved CDs safe effective fluorescent material used (TNP, HClO) actual water sample.
