Simultaneous determination of 10 trace metal elements in surface water by ICP-MS
A method for simultaneous determination of 10 trace metal residues in surface water by inductively coupled plasma mass spectrometry(ICP-MS)has been developed.The 10 metal elements had good linear relationship in the range of 1.00～80.0μg·L-1,and the correlation coefficients were all greater than 0.999.The results of the method were all within the guaranteed value range,the relative standard deviations were all less than 4%(n=6),and the recoveries of the samples were 87.8%～105.5%.With low detection limit,high sensitivity and accurate test results,this method can be used for the analysis of copper,lead,cadmium,molybdenum,chromium and other metal residues in surface water.
