火焰原子吸收光谱法具有装置简单,分析速度快,测量精度高和基体效应小等优点。因此,在各个领域中得到了广泛应用。但是,由于火焰法的雾化效率低,限制了灵敏度的进一步提高。 1976年以来,水冷石英管作为原子捕集器用于火焰原子吸收分析已有报导,近年来国内在这方面也开始进行了研究。本文研究了原子捕集火焰原子吸收光谱法测定人参及长春南湖水中微量锌的最佳实验方案。对人参样品测量的相对标准偏差为 Flame atomic absorption spectrometry has the advantages of simple device, fast analysis, high measurement accuracy and small matrix effect. Therefore, it has been widely used in various fields. However, due to the low atomization efficiency of the flame method, the sensitivity is further limited. Since 1976, the use of water-cooled quartz tube as atomic trap for flame atomic absorption spectrometry has been reported. In recent years, research on this field has also been conducted in China. In this paper, the best experimental scheme for the determination of trace zinc in ginseng and Changchun South Lake by atomic absorption spectrometry (FAAS) was studied. The relative standard deviation of ginseng samples was measured
