| Abstract: | The uncertainty of the determination of chromium in the phosphate rock by flame atomic absorption spectrometry( FAAS) was studied. Firstly,the preparation of experimental instruments and experimental reagents is introduced. Then,the sources of uncertainty in the experiment are studied and analyzed. Finally,the synthetic uncertainty is calculated. |
