Abstract
To determine the trace elements such as beryllium,magnesium,calcium,vanadium,chromium,manganese,cobalt,nickel,copper,zinc,arsenic,selenium,molybdenum,silver,cadmium,antimony,barium,thallium,lead,uranium and thorium in surface water with interior standard materials which are 6Li、Sc、Ge、Y、In、Bi as calibration system by ICP-MS.Results showed that the linear coefficients of the 21 kinds of trace elements were better than 0.999 5.Detection limits of the method were 0.006~0.730 μg/L.Testing values of standard sample were in the scope of the guarantee and its RSD was less than 4.22%.Recoveries of the spiked samples were 95.0%~116.1%.关键词
