摘要
Platinum-group metals are in increasing demand for industrial use. Herein, we present a fluorometric method for palladium detection that can be used to prioritize ore samples on site. The analyses of solid ore samples were sufficiently correlated with that of aqua regia extracts of the same ore samples. Twenty samples could be analyzed in parallel and more samples can be if so desired due to the high throughput nature of the assay method. Although the correlational study was performed after 90 min incubation, 30 min incubation was sufficient to obtain strong fluorescence signals (i.e., 1.5 min per sample). Given the visible nature of the green fluorescence and the procedural simplicity, palladium and coexisting platinum ores are identifiable in the field with the naked eye.
