Arsenic, selenium and mercury in biological samples were digested wetly and continuous determined by the double channel atomic fluorescence spectrometry.The pretreated method and experimental conditions were optimized.The method is rapid,simple,accurate,sensitive and good reproducibility. The detection limits were 0.0158μg/L for As,0.0645μg/L for Se and 0.0014μg/L for Hg,the precision RSD (n = 12) was less than 5.75%,the recovery of the elements were greater than 95.5%, The determination of national biological ingredients standard material,result in accordance with the standard values.
