| Abstract: | Objective:To establish flame atomic absorption method for direct determination of Fe content in drinking water.Methods: La2O3 was added into water samples to optimize the instrument condition.Then Fe content was directly determined by flame atomic absorption meter.Results: The linear range of the method was 0.00 mg/L~2.00 mg/L with correlation coefficient of 0.99962.The recovery was 96%~105%,RSD(%) was 0.47%~1.85%,the detection limit was 0.026 mg/L.Conclusion: This method had the advantages of simple operation,low detection limit,good precision and reliable accuracy. |
