[Determination of 23 elements in beverages by FAAS and ICP-MS].
23 elements in 11 kinds of beverages were determined by FAAS and ICP-MS. The effects of nitric acid and coexist elements on FAAS determination were studied and the experimental conditions were optimized. The results show that these beverages contain abundant inorganic elements like K, Na, Ca and Mg, which are important for human being. The content of trace elements As, Pb, Cu, Zn and Fe are under the tolerance limit of GB standard.
