Abstract:
Hydrazine (N2H4) is being extensively utilized in various industrial fields, yet its high toxicity can cause enormous adverse effects on human health and the ecological environment. Herein, an aggregation-induced emission (AIE) fluorescent probe FNA-B-CA (naphthalimide small molecule (FNA-B) grafting onto cellulose acetate (CA)) for sensitive detection and high effective removal of N2H4 was synthesized. Probe FNA-B-CA can recognize N2H4 across a wide pH range (5 -12) with a low detection limit (84 nM), high selectivity, and strong anti-interference ability. It enabled quantitative detection of N₂H₄ concentrations in actual water and soil samples quantitatively and functioned as an efficient tool for tracking N2H4 in plant tissue (bean sprouts). More importantly, probe FNA-B-CA was hereby successfully prepared into fluorescent microspheres using the favorable processing properties of CA, further facilitating the simultaneous detection and adsorption of N2H4 in aqueous solutions.
