Abstract

Application of CARBON QUANTUM DOTS as nano SENSORs for determination of ions and molecules is an effective, fast, cheap, and environmentally friendly method and no need to complex equipment. In the present study, Mo (VI) was determined by CARBON QUANTUM DOTS in real samples such as tap, mineral, river waters, and tomato samples. CARBON QUANTUM DOTS were synthesized by microwave assisted method. Fourier transform infrared (FT-IR) and transmission electron microscope (TEM) were used for characterization and size determination of these CARBON QUANTUM DOTS. At optimum conditions (pH=3, lex = 370 nm and lem = 450 nm), detection limit and linear dynamic range were 24 nM and 0.2- 50 mM, respectively. Fluorescent quenching process was very fast that was an important advantage of this nanosensor. Interference effects of other ions on Mo (VI) determination (at constant concentration of 25±0.072 mM, n=3) by CARBON QUANTUM DOTS were investigated in the presence of different concentration of other species.
