高分辨连续光源原子吸收光谱仪检测饮用矿泉水中的金属离子

High-resolution Continuum Source Atomic Absorption Spectrometer and Its Application in Determination of Metal Ions in Drinking Mineral Water

简要介绍了高分辨连续光源原子吸收光谱仪（HS—CS—AAS）的基本特点，并利用HS—CS—AAS测定了饮用矿泉水中的钙、镁、锶、钾、钠等微量元素。结果表明，测定各种离子的加标回收率为96．2％～100．9％，相对标准偏差（RSD，n=7）为0．44％～4．90％。

The basic characteristics of high-resolution continuum source atomic absorption spectrometer （HS-CS-AAS） is introduced in this paper and a method based on the instrument for the determination of trace metal elements of calcium, magnesium, strontium, potassium and sodium in drinking mineral water has been developed. The recovery of the method is 96.2% - 100.9% with precision of 0.44% - 4.90% RSD （n = 7）.
