[Determination of aluminium in healthy person's hair by FAAS and FAES]

In this paper, two methods of N2O/C2H2 FAAS and FAES are applied to determine aluminium in healthman hair. The requirement of determination, interferences of inorganic ions and organic substances and the results of determination are contrasted respectively. It is shown experimently that the interference ratio of substances, accuracy, sensitivity and recovery ratio of FAES are superior to FAAS at 396.1 nm wavelength in acidity medium. The RSD (n = 9) of FAES and FAAS are 2.2 and 2.7% respectively and detect limit is 0.07 microg/mL for FAES and 0.25 microg/mL for FAAS. The recovery ratio of adding 20.0 microg aluminium to 1.0 g hair samples are 96.5-105.0% and 93.5-106.5% respectively.
