原子吸收光谱法对瓶装饮用水中Cd、Cu、Pb、Fe、Zn的分析

Determination of Cd,Cu,Pb,Fe,Zn in Bottled Drinking Water through Atomic Absorption Spectrometry Method

以10种不同品牌的市售瓶装饮用水为研究对象,运用石墨炉原子吸收法和火焰原子吸收法对其Cd、Cu、Pb、Fe、Zn5种重金属元素的含量进行分析,以了解不同品牌的瓶装饮用水中重金属元素的含量情况。研究结果表明:10种市售瓶装饮用水中的Cd、Cu、Pb、Fe、Zn 5种重金属含量均达到国标要求。

10 different brands of commercial bottled drinking water for the experimental materials,using graphite furnace atomic absorption and flame atomic absorption spectrometry,the bottled water Cd、Cu、Pb、Fe、Zn five heavy metals were determined to understand the different brand bottled drinking water content of the five heavy metals.The results showed that：The whole bottled water content of the five heavy metals Cd、Cu、Pb、Fe、Zn are up to national standard requirements.
