Abstract
Hydrazine (N2H4), one of the common industrial chemicals, possesses not only wide application field, but also causes serious threats to the environment and human beings. It is necessary to establish a simple, rapid and accurate method for detection of N2H4 in the environment and living organism. In this work, a flavonol derivative-grafted ethyl cellulose-based fluorescent probe EC-OME was designed and synthesized for the efficient detection of N2H4 using ethyl cellulose and flavonol derivatives as the raw materials. The structure of EC-OME was characterized with FT-IR, and the fluorescence properties of EC-OME to N2H4 were investigated by fluorescence spectroscopy. It was verified that this probe has good selectivity, anti-interference ability and photostability with a detection limit for N2H4 as low as 0.229 μM and a response time of 30 min, which can be used for determining N2H4 in real environmental water and soil samples. Furthermore, probe EC-OME has been successfully applied to the fluorescence imaging of N2H4 in live zebrafish, showing the great potential for environmental trace N2H4 detection.
