摘要
采用RA-915M汞分析仪结合不同附件,用2种分析方法(即电热—塞曼效应原子吸收分光光度法和微波消解—冷原子吸收分光光度法)测定了同一土壤样品中的总汞含量并对2种方法做了介绍和对比。数据分析表明2种方法均有很好的准确度和稳定性。此外,电热—塞曼效应原子吸收分光光度法还具有效率高、成本低的优点。
In this paper, determination of total mercury in soil were all done by RA -915M mercury analyzer based on the em- ployment of atomic adsorption spectrometry with Electric - Zeeman effect in contrast to the microwave digestion - cold vapour atomic absorption spectrometry. The results showed that both methods can offer suitable accuracy and stability. In addition, without any pretreatment of the soil samples, the applied electric - Zeeman effect atomic absorption spectrophotometry was also highlighted with high efficiency and low cost.
