[Study on determination of 24 elements in drinking water-related products by soaking experiment with inductively coupled plasma-mass spectrometry].
OBJECTIVE
To establish an analytical method for determining 24 metals in drinking water-related products by soaking experiment.


METHODS
Inductively coupled plasma-mass spectrometry (ICP-MS) was applied to determine 24 metals in drinking water-related products by soaking experiment with using Sc, Ge, Y, In, Tb and Bi as an internal standard.


RESULTS
The correlation coefficient r value, recovery rate, relative standard deviation was 0.999 - 0.9999, 83 % - 125 % and 0.32% - 8.8% (except Zn 11.2%). The working curve of Sn was prepared with soaking water. The matrix is noninterference. The results showed close agreement with the reference values in standard reference materials.


CONCLUSIONS
It indicates that the method is simple, rapid, sensitive and accurate, which can meet the demand for 24 elements analysis in drinking water-related products by soaking experiment.
