原子吸收法测定饮用水中微量元素

Determination of the Content of Trace Elements in Drinkable Water by Atomic Absorption Spectrometry

火焰原子吸收法测定地下水、矿泉水和桶装水中微量元素。仪器经过最佳优化选择，测定每种水样的微量元素含量，实验表明，饮用水中铜、锌、铬含量都符合国家标准，镍未检出，各元素标准曲线线性好，铜、锌、镍、铬定量的相关系数值在0.9900～1.0000范围内，该实验方法简单、快捷、准确，结果令人满意。

Determination the content of trace elements in groundwater , mineral water and bottled water by atomic absorption spectrometry , after selecting the best optimization parameters of AAS , it measured the trace element content of water samples.Experiments showed that drinkable water in copper , zinc, chromium contents are in line with national standards and nickel was undetected.The element standard curve was linear , copper, zinc, nickel, chromium curve correlation coefficient was in the range of 0.9900 ~1.0000.The method was simple , fast and accurate , and it gave satisfactory results.
