关于在原子吸收上测铜元素的方法

Atomic absorption spectrometry and its application

传统的荧光光谱法可直接对金属元素进行无损检测,但是存在灵敏度低、选择性差等问题,为此,对原子吸收光谱法及其应用进行了研究。由于对样本的预处理和导入技术在整个测试环节中占据重要的地位,因此对其进行了详细的分析。采用脉冲悬浮法对样本进行分离与富集,并将样本导入。原子吸收光谱法具有消除基体干扰,提高灰化温度的优势,同时还具有灵敏度高、选择性强等特点,被广泛的应用到各个领域当中。

Traditional fluorescence spectrometry can be used to detect metal elements directly, but it has some problems such as low sensitivity and poor selectivity. Because the sample pretreatment and import technology occupies an important position in the whole testing process, so it is analyzed in detail. Samples were separated and enriched by pulsed levitation method, and samples were imported. Atomic absorption spectrometry（AAS） has been widely used in various fields because of its advantages of eliminating matrix interference and increasing ashing temperature, as well as its high sensitivity and selectivity.
