摘　　要：目的研究吉林市市售饮用水中矿物质含量,为市民合理选择饮用水提供科学依据。方法分别采用原子吸收分光光度法、原子荧光分光光度法对吉林市售饮用水中矿物质进行测定。结果市售饮用水中均含有不同浓度的矿物质元素,其中苏克苏打水中Na含量最高,达(119.258±0.013)mg/L,曲玛弄矿泉水中K含量最高,达(25.551±0.008)mg/L,瑞碧斯中Ca含量最高,达(93.413±0.017)mg/L,恒大冰泉和昆仑山矿泉水中镁含量相对较高,曲玛弄矿泉水和N47°苏打水未检出Mn元素,其他饮用水中均含有少量的Mn、Fe和Cu元素,所检样品中均未检出Zn、Hg和As。结论吉林市售不同饮用水中所含有的矿物质存在一定的差异,且饮用水中都没有检测出重金属,所分析的饮用水矿物质含量均符合国标标准。Objective the analysis of minerals choice of drinking analyzed by atomic water The mineral elements in drinking water play an important role in the human body. Therefore, content in drinking water on market of Jilin City provides important basis for the reasonable for citizens. Methods The mineral elements in drinking water on market of Jilin City were absorption spectrometry, atomic fluorescence spectrophotometry, respectively. Results Drinking water on market contains different concentrations of mineral elements, which Na content is the highest in suker soda water （119. 258 ±0.013 ）mg/L,while the K content is the highest in Qu Manong mineral water （25. 551 ±0. 008 ） mg/L, the Ca content is （93. 413 ± 0. 017）mg/L in Rui Bisi water, and the Mg content is relatively higkin the Evergrande ice fountain water and the Kunlun mineral water. There are not Mn element in Qu Manong mineral water and N47° soda water, the other kinds of drinking water containing a small amount of Mn, Fe and Cu elements. We did not detect Zn,Hg and As elements in the test sample. Conclusion The mineral elements appear differences in drinking water on market of Jilin City, and heavy metals in drinking water are not detected. The mineral contents in drinking water are conform to GB of drinking water.
