AB  - Objective: To establish a method for the determination of manganese in urine by 
      graphite furnace atomic absorption spectrometry (AAS) without the use of matrix 
      modifier. Methods: The urine samples were 5 times diluted with 1% nitric acid 
      then directly determined by AAS. Zeeman was used for background correction. 
      Results: The linear range for determination of manganese in urine was 5~60 mug/L 
      (urine) . The correlation coefficient was greater than 0.995 with the detection 
      limit of 1.5 mug/L and with the lower limit of quantification of 5.0 mug/L. The 
      relative standard deviations (RSDs) of within-run precision was between 
      1.1%~4.3%, the RSDs of between-run precision was between 3.3%~7.0%. The average 
      recovery was 102.6%. The samples can be stored for 14 days at room temperature, 
      4℃, -8 ℃ and -35 ℃. Conclusion: The method is feasible for determination of 
      manganese in urine.
