AI Technical Summary
Existing technologies cannot simultaneously detect copper and iron ions quickly and visually, and most fluorescent probes are only visible under ultraviolet light, lacking a detection method that allows for color changes to be discerned with the naked eye under sunlight.
A Schiff base compound was developed to prepare a fluorescent probe by reacting 2-furanoylhydrazide with 4-dimethylaminocinnamaldehyde. Using dimethylamino as an auxochrome, a dual-response quenching recognition of Cu2+ and Fe3+ was achieved, exhibiting a clear color change under fluorescent light. The probe was then combined with a portable test strip and kit for detection.
It enables rapid and visual detection of Cu2+ and Fe3+, with high sensitivity and selectivity. Color changes can be observed with the naked eye under sunlight, meeting the needs of portable detection.
