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.

纤维素基荧光微球用于肼的灵敏检测和高效去除及其在环境样品和活植物中的广泛应用

肼（N2H4）广泛应用于各种工业领域，但其高毒性对人类健康和生态环境造成巨大的不利影响。本文合成了一种聚合诱导发射（AIE）荧光探针FNA-B-CA（萘酰亚胺小分子（FNA-B）接枝到醋酸纤维素（CA）上），用于灵敏检测和高效去除N2H4。探针FNA-B-CA能在较宽的pH范围（5 ~ 12）内识别N2H4，检出限低（84 nM），选择性高，抗干扰能力强。它可以定量检测实际水和土壤样品中的N₂H₄浓度，并作为跟踪植物组织（豆芽）中N2H4的有效工具。更重要的是，利用CA良好的加工性能，本文成功地将探针FNA-B-CA制备成荧光微球，进一步促进了水溶液中N2H4的同时检测和吸附。

期刊介绍： The Journal of Hazardous Materials serves as a global platform for promoting cutting-edge research in the field of Environmental Science and Engineering. Our publication features a wide range of articles, including full-length research papers, review articles, and perspectives, with the aim of enhancing our understanding of the dangers and risks associated with various materials concerning public health and the environment. It is important to note that the term "environmental contaminants" refers specifically to substances that pose hazardous effects through contamination, while excluding those that do not have such impacts on the environment or human health. Moreover, we emphasize the distinction between wastes and hazardous materials in order to provide further clarity on the scope of the journal. We have a keen interest in exploring specific compounds and microbial agents that have adverse effects on the environment.
