| Abstract: | The uncertainty of determination of magnesium oxide content in phosphate rock by flame atomic absorption spectrometric method was evaluated.The main sources of uncertainty were analyzed,which included synthesizing of standard curve,the uncertainty of the standard solution,the weight and foreordain disposal of the sample so on.By evaluation,the uncertainty of synthesizing the standard curve plays the largest role in all. |
