| Abstract: |
| In this paper, the two methods of atomic absorption spectrometry and inductively coupled plasma multielement determination are discussed. The atomic absorption method of tri acid solution needs to be added to the potassium sulfate as an ionization inhibitor. The operation is complex but the detection limit is lower and the linear range is narrow. The plasma spectrometric method of four acid soluble samples is simple and rapid, and is suitable for rapid determination of large quantities and multielements. The combination of the two methods can achieve rapid, simple and accurate detection of rubidium in large quantities of samples. |
