Fluorescent carbon nanoparticles for sensitive and selective detection of palladium (Pd²+)

Reaction-Based Multisignal Detection of Palladium with High Sensitivity, Selectivity, and Reliability

“…However, these methods for quantifying residual palladium are generally instrumentally intensive and performed off-site and thus require long analysis time ranging from days to even weeks. Awual et al recently developed a series of adsorbents for detection and recovery of trace-level Pd. ,, Trace metals could be conveniently monitored by fluorometric methods that are more amenable to on-site operation. , The reaction-based FL approach for sensing has especially increased attention due to its high sensitivity and selectivity. , In recent years, researchers have developed various fluorogenic reactions for palladium detection. Pd-catalyzed cyclization, rearrangement, depropargylation, , deiodination, Heck, , and Tsuji–Trost − coupling reactions were previously reported to build reaction-based fluorescent palladium probes.…”
