【Abstract】 In this paper,flame atomic absorption spectrometry(FAAS) using the slotted atom-trapping technique(SATT)with a quartz tube was studied for manganese determination. The effects of air current, position of light beam,position of flame combustioner and structure of the slotted tube on the analytical sensitivity was examined. Appropriate conditions for determination of manganese are established.This method yielded 3.4 times the sensitivity of convemtional FAAS.更多还原
