Abstract:

The three elements,As,Sb,Bi, the same as Ag,Au,Cu, Hg, Mo, Pb, Sn, W,Zn,are important indicated elements in looking for gold mine, which are usually determined by atomic fluorescent spectrometer (AFS). Since the conditions of their hydride generation are different and the contents among them have no proportion relation, they can't be determined simultaneously. And because the dynamic range of AFS is narrow,the samples must be diluted or weighed again if the content of a certain element is too high or low.
