AI Technical Summary

Technical Problem

Existing technologies and traditional detection methods for metal ions and nitroaromatic explosives are complex to operate, require inconvenient equipment, and are costly. They lack rapid, convenient, and low-cost detection methods. Furthermore, the synthesis of fluorescent materials is costly and the synthesis process is not environmentally friendly.

Method used

A zinc-based fluorescent probe containing a pyridyl carboxylic acid type component was designed and prepared by a solvothermal method using Zn(C22H14N3O2)(CHO2)(H2O)·C3H7NO·3H2O. As a bifunctional fluorescent sensor, it can detect Fe3+ and 2,4,6-trinitrophenol in N,N-dimethylformamide solution with high sensitivity and high selectivity.

Benefits of technology

A fluorescent material with high thermal stability and high pyrolysis temperature has been developed. The preparation method is simple, environmentally friendly and low cost. It can quickly and accurately detect Fe3+ and TNP, and has good reproducibility and selectivity.
