Abstract:
Objective To establish a simple, sensitive and accurate analytical method to determine 15 elements in drinking water-related products soak test. Methods Inductively coupled plasma-mass spectrometry (ICP-MS) was employed to determine 15 elements in the soaking liquid. Sc, Ge, In and Bi were used as the internal standard substances. Results The test results showed the linear correlation coefficients for all elements were more than 0.999, the recovery rate were 80.6%-120.0% and precision was fine, RSD was lower than 6.0 %, the test results also showed a close agreement with the reference values in test of reference materials of GSBZ 50009-88, GSBZ 500019-90, GSBZ 50004-88 and GSBZ50039-95. Conclusion This method is simple, rapid, sensitive, accurate and suitable for determination of 15 elements in drinking water-related products soak test.
