利用电感耦合等离子体质谱仪的高灵敏度、高准确性和多元素同时分析的特点,可以快速精确地测定自来水中的微量金属元素含量。由于自来水样品中的有害金属元素含量比较低,需要高灵敏度的分析方法,所以与其他元素分析技术相比ICP-MS优势明显,在自来水样品分析中已经得到了广泛的应用。本文用电感耦合等离子体质谱法(ICP-MS)和原子吸收分光光度法(AAS)测定自来水中的金属元素,并对中国与日本自来水进行了取样分析和比较。
The high sensitivity, high accuracy and simultaneous multi-element analysis of ICP-MS make it possible to quickly and accurately determine the trace metal content in tap water. Due to the relatively low content of harmful metals in tap water samples and the need for highly sensitive analytical methods, ICP-MS has obvious advantages over other elemental analytical techniques and has found wide application in tap water sample analysis. In this paper, inductively coupled plasma mass spectrometry (ICP-MS) and atomic absorption spectrophotometry (AAS) were used to determine the metal elements in tap water. Samples of tap water in China and Japan were analyzed and compared.
