石墨炉原子吸收中铜、锌基体的背景吸收影响

The Influence of the Copper and Zinc Matrix on the Background in the Furnace Atomic Absorption Spectroscopy

研究了石墨炉原子吸收中铜、锌氯化物和硝酸盐的背景吸收影响。背景吸收的波长特性和时间特性的研究表明,铜、锌氯化物的背景吸收比硝酸盐具有更明显的波长特性,而硝酸盐的背景吸收具有更广泛的时间分布,二者在相同的条件下,铜、锌氯化物的背景吸收较大。

In this paper,the influence of copper and zinc chlorides and their nitrates on the background in the furnace atomic absorption spcctroseopy are discussed.The characteristics of the time and wavelength of the background were studied.The results showed the wavelength character of the background of copper and zinc chlorides is more obviouse than their nitrates,the time distribution of She nitrate background is more extensive.Under the same conditions,the background of copper and zinc chlorides is much higher than their nitrates.
