Determination of Trace Elements in Water by Inductively Coupled Plasma Mass Spectrometry

The application of inductively coupled plasma mass spectrometry for water samples(surface water,drinking water,etc.),copper,zinc,selenium,arsenic,cadmium,chromium,lead,iron,manganese and other trace elements were analyzed.The results showed that the detection limit was 0.01~0.78 μg/L,the relative standard deviation of parallel samples was 0.6% to 7.9%,and the recovery of added standards in water samples ranged from 90.5% to 103%.The method was rapid,simple,linear range and good detection limits and accuracy.
