含氧有机物对碱金属火焰原子发射光谱发射强度的影响规律

The Influence of Oxy-Organics on the Emission Intensity of Flame Atomic Emission Spectrometry(FAES) of Alkali Metals

火焰原子发射光谱法(FAES)常用于分析检测碱金属各元素。实验结果表明,当试样中含有在水中溶解度较大的含氧有机物时,会对碱金属元素的火焰原子发射辐射强度产生影响。不同种类,不同浓度的含氧有机物使碱金属元素的发射强度改变的幅度是不同的,影响规律也有很大差异。有机物同分异构体以及官能团数量上的差异也对碱金属元素的发射强度产生影响,其影响规律也不相同。

Flame atomic emission spectrometry（FAES） is frequently used to analyze various alkaline elements. The effects of concentrated oxy-organics in water solution on the radiation intensity of alkaline elements FAES were studied. The species and concentration of oxy-organics may affect the radiation intensity variation amplitude of alkaline elements and also the tendency of the mutation can be different dramatically. Similarly, the emission intensity of alkaline elements can be affected by isomers or variation of the quantity of functional group, and the trend is different either.
