原子吸收光谱法检测饮用矿物质水中的金属元素

Determination of metals in mineral water by atomic absorption spectrometry

研究了火焰原子吸收光谱法检测饮用矿物质水中的金属元素钾、钙、锰、钴、镍、锌的含量。对最佳仪器条件进行研究,使被测元素的浓度与吸光度值呈线性关系,相关系数R都不小于0.999 4,样品测定结果令人满意。

The atomic absorption spectrometry was used to determine the content of K, Ca, Mn, Co, Ni,Zn in mineral water. The analysis of the best working parameter of the instrument was researched, and the el- ement concentration has linear relationship with absorbance. The relative coefficient R was not less than 0.999 4. The results of the samples are very satisfied.
