【Abstract】 Inductively coupled plasma-mass spectrometry (ICP-MS) was applied to determine 23 elements in drinking natural mineral water by using Sc、Ge、In、Bi as an internal standard. The experimental results showed the linear correlation factor for all elements are higher than 0. 999. Recoveries of spiked samples were in the range of 87.6%—107.4% and precision was fine, RSD is lower than 4.0%. And the results showed close agreement with the reference values in three standard reference materials of GSBZ5009-88, GSBZS0020-93(3)and GSB07-1375-2001. It indicated that the method is simple, rapid, sensitive and accurate, which can meet the demand for 23 elements analysis in drinking natural mineral water.更多还原
