铂族金属在工业用途中的需求日益增加。在此，我们提出了一种荧光法钯检测，可用于优先矿石样品现场。固体矿石样品的分析与同一矿石样品的王水提取物的分析具有充分的相关性。由于测定方法的高通量性质，可以平行分析20个样品，并且如果需要，可以分析更多样品。虽然相关性研究是在90分钟孵育后进行的，但30分钟孵育足以获得强荧光信号（即，1.5 min/样品）。鉴于绿色荧光的可见性质和程序的简单性，钯和共存的铂矿石在现场用肉眼是可识别的。
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.
