| Abstract: | The main source of the uncertainty of measuring ferrum with ferrosin spectrophotometric method is analyzed,calculated and synthesized.The uncertainty in detecting ferrum by ferrosin spectrophotomotic is ±0.327 mg/L.The main source of uncertainty in detecting ferrum by ferrosin spectrophotometric arise from repeated measurement of the sample and the combination of standard curve. |
| Keywords: | ferrum spectrophotometric uncertainty evaluate |
