| Abstract: | [ Objective ] To establish a method for determination of aluminum in urine by graphite furnace atomic absorption spectrometry （GFAAS）. [ Methods ] Samples were diluted with 0.10% TritonX-100 and 0.50% HNO. Concentrations of urinary aluminum were detected by GFAAS. [ Results ] The correlation coefficient was 0.999, the limit of detection was 1.02 ~tg/L, the recovery rate ranged from 91.8% to 104.9%, with the relative standard deviation of 3.9%-7.9%. The urine samples could he stored at 4% for at least 14 days. [ Conclusion ] The method is sensitive, convenient, and accurate, and thus can he used to determine aluminum in urine. |
