文摘
- •
Fluorescent Ag nanoclusters were first applied to Cr(VI) detection.
- •
The proposed method is simple, rapid, and environmentally friendly.
- •
The sensor shows a wide linear range, low detection limit, and good selectivity.
- •
The system can also be used for the indirect assay of total chromium and Cr(III).
- •
The analyses in real water samples are satisfactory.
