Objective：To present a novel method for the determination of trace - aluminium in human serum album. Methods： The trace - aluminum in human serum album was determined by graphite furnace atomic absorption spectrometry with transverse heated graphite atomizer（THGA）system and Zeeman background correction. Results： The method characteristic mass was 39. 7 pg,the detection limit was 0. 51 ng ·mL^-1 ,RSD was 8.2% and recovery rate was 90. 2% -103. 2%. Conclusion ：The proposed method offers simple instrumental operation, high sensitivity and accuracy.
