| Abstract: | The effects of background absorption of Lu, Yb matrices in graphite furnace atomic absorption spectrometry were investigated. The experiments demonstrate that the background absorption of Lu, Yb matrices are obviously wavelength dependent. The peak heights of background matrices are related to ashing temperature. The outlines of background distribution are related to the atomization temperature and heating mode of atomization. The method of reducing the background absorption of LuCl 3 and YbCl 3 is also discussed. |
