Abstract
The present invention discloses a fluorescent probe compound which solved the problem of fluorescence quenching by Pd, and its preparation method and use as well. Excitation and emission wavelengths of the probe compound are in visible light region. The probe compound is highly sensitive and displays good selectivity for Pdin near-neutral pH range. In detection of Pdin 0-10 ppb level, fluorescence is evidently enhanced, and Pdin the level as low as 5 nM can be detected. Fluorescence intensity is well linearly correlated to Pdconcentration. The probe compound can be used for detection of contaminating palladium and residual palladium in drug, soil, water sample and reactor.
