- Abstract
Cellulose is the most abundant natural polymer with good biodegradability and biocompatibility. In this paper, a novel fluorescent probe DAC‐SD‐NA for aluminum (Al3+) detection is successfully synthesized based on dialdehyde cellulose (DAC). DAC‐SD‐NA exhibited a remarkable "turn‐on" fluorescence response to Al3+ in a wide pH range, and the fluorescence color of DAC‐SD‐NA solution turned from colorless to bright blue at the presence of Al3+. The detection limit for Al3+ is computed to be 6.06×10−7m. The reaction mechanism of DAC‐SD‐NA towards Al3+ is confirmed by Job's plot, X‐ray photoelectron spectroscopy, and density functional theory (DFT) calculations. In view of DAC‐SD‐NA exhibited good sensitivity and selectivity, it is applied to detect Al3+ in real water. What's more, DAC‐SD‐NA‐loaded fluorescent hydrogel can serve as a convenient tool for the detection of Al3+.
