火焰原子吸收光谱法测定预熔型精炼渣中的氧化镁

Determination of magnesium oxide in premelted refining slag by Flame Atomic Absorption Spectrometry

火焰原子吸收光谱法具有精密度高,抗干扰能力强而且较为灵敏的特点,而且实际应用过程中操作较为方便,使用的仪器简单。在操作的过程中,仪器从光源辐射出具有待测元素特征的光,并且对光进行处理,主要是利用试样蒸气时被蒸气中待测元素基态原子所吸收,而且就可以进行分析,通过光谱减弱的程度来对待测元素的含量进行测定。本文具体分析研究火焰原子吸收光谱法测定预熔型精炼渣中的氧化镁的具体应用。

Flame atomic absorption spectrometry has the characteristics of high precision,strong anti-interference ability and sensitivity,and it is easy to operate and simple to use in practical application.In the process of operation,the instrument radiates the light with the characteristics of the elements to be measured from the light source,and processes the light,mainly using the sample steam to be absorbed by the ground state atoms of the elements to be measured in the steam,and then it can be analyzed,and the content of the elements to be measured can be determined by the degree of spectral weakening.In this paper,the application of flame atomic absorption spectrometry to the determination of MgO in premelted refining slag is studied.
