This standard specifies the method for the determination of rubidium and chromium by flame emission spectrometry. This standard is applicable to the determination of rubidium and chromium content in groundwater. The optimal measurement range is 0.02~2.Omg/L. It interferes with other alkali metals and has a sensitizing effect, so the potassium and sodium content in the sample and standard solution should be controlled to be consistent.
