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.
Conclusion:
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.
