One-Step Hydrothermal Synthesis of Fluorescent Carbon Dots and Fe3+ Detection
Abstract
Carbon dots (CDs) are of great significance for metal ion detection. Herein, CDs without surface functional groups were synthesized through a simple one-step hydrothermal method using 4,4 '-bipyridine as the carbon source. The results showed that the synthesized CDs have good selectivity for Fe3+ detection, and the CDs respond well to metal ions as Lewis bases. This detection method is unlikely to be affected by sewage systems because it has excellent sensitivity. The detection range for Fe3+ concentrations is between 1.0×10-8 and 1.0×102 mol/L, and the detection limit is 1.0×10-8 mol/L.
