2 Normative references

The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 6682 Analytical laboratory water specifications and test methods

3 Method summary

The sample is evaporated by low temperature to remove alcohol, and after digestion and constant volume, it is injected into an inductively coupled plasma mass spectrometer to establish concentration and quality in a certain range. The standard curve of the spectral signal is obtained by intensity comparison to obtain the content of rare earth elements in the sample solution.
