| Abstract: | The method to determine aluminum in seaweed by microwave digestion-GFAAS is studied.After optimizing determination conditions.the developed method meets the current standards for precision and accuracy requirements.The results show that the content of aluminum is linear in the range of 0～100 μg/L.The Correlation coefficient is 0.9990.The relative standard deviation is 4.12%.The ratio of recovery was 90%～105%.The developed method is suitable for determination of aluminum in seaweed with rapid,accurateness,high sensitivity. |
