ICP-Mass Spectrometric Determination of Trace-Elements in Water

Fifty-one trace-elements in water (underground water,groundwater,drinking water and etc.) were determined simultaneously by ICP-MS.Analytical conditions,including the choice of isotopes for determination,working parameters of the instrument and test for precision and limits of detection etc.,were studied.Values of the 51 elements determined by this method checked quite well with the standard values,giving relative deviations less than ±10% (besides tungsten).Results of recovery tests were in the range of 90%-110%.
