| 摘 要： | 本文研究石墨炉原子吸收光谱中铁、铝的氯化物和硝酸盐的背景吸收影响.背景吸收波长特性的研究表明,铁、铝氯化物和硝酸盐的背景吸收都具有明显的波长特性.氯化铝和硝酸铝的背景吸收曲线基本重合,而硝酸铁较氯化铁的背景吸收要小得多.时间特性的研究表明,在某些情况下,可以通过选择记录原子吸收信号的时间来减小甚至完全消除背景吸收干扰.

| Abstract: | The influence of the background of aluminium and iron nitrates and chlorides in graphite furnace atomic absorption spectroscopy has been studied. The background absorption is significantly wavelength-dependent.The curves of the backgrounds of A1C13 and and Al ( NO3 )3 are basically overlapped, while the background absorption of Fe ( NO3 )3 is much smaller than that of FeCl3. The studies of the atomization time vs absorbent curves show that the background interference can be reduced,even eliminated by choosing an appropriate signal recording time. |
