Sensitive, Selective and Reliable Detection of Fe<sup>3+</sup> in Lake Water via Carbon Dots-Based Fluorescence Assay
In this study, C-dots were facilely synthesized via microwave irradiation using citric acid and ethylenediamine as carbon precursors. The fluorescence emissions of the C-dots could be selectively quenched by Fe<sup>3+</sup>, and the degree of quenching was linearly related to the concent...

description | In this study, C-dots were facilely synthesized via microwave irradiation using citric acid and ethylenediamine as carbon precursors. The fluorescence emissions of the C-dots could be selectively quenched by Fe<sup>3+</sup>, and the degree of quenching was linearly related to the concentrations of Fe<sup>3+</sup> presented. This phenomenon was utilized to develop a sensitive fluorescence assay for Fe<sup>3+</sup> detection with broad linear range (0–250, 250–1200 μmol/L) and low detection limit (1.68 μmol/L). Most importantly, the assay demonstrated high reliability towards samples in deionized water, tap water and lake water, which should find potential applications for Fe<sup>3+</sup> monitoring in complicated environments. |
