ICP-MS用于测定特定地区饮用水中金属元素总量

Determination of the total amount of metal elements in drinking water in specific areas by ICP MS

运用电感耦合等离子体质谱法(ICP-MS)对大同市饮用水金属元素总量进行检测。结果表明,共发现16种金属元素,排名前五的金属元素分别为:Ba为39.51μg/L、Zn为12.03μg/L、Sb为3.43μg/L、Cr为2.30μg/L、Ni为2.10μg/L;As、Sb超标;Co与Ni、Mn,Ni与Cu、As、Ti、T1,Cu与As、Ti、T1,As与Ti、T1,Zu与Cd,Ti与T1之间均显著相关(P<0.01),同时Be与Cr,Co与Cu、As、Ti、A1,Ni与V,Be与Cu、T1之间有相关相关性(P<0.05)。得出结论,大同市饮用水部分元素含量较高,大部分金属元素具有共同来源,必须引起重视。

The total amount of metal elements in drinking water in Datong was detected by inductively coupled plasma mass spectrometry（ICP MS）.The results showed that 16 metal elements were found,and the top five metal elements were Ba39.51 mu g/L,Zn 12.03 g/L,Sb 3.43 mu g/L,Cr 2.30 mu g/L,Ni 2.10 mu g/L.As and Sb exceeded the standard.Co is significantly correlated with Ni,Mn.Ni is significantly correlated with Cu,As,Ti,T1.Cu is significantly correlated with As,Ti,T1.As is significantly correlated with Ti,T1.Zu is significantly correlated with Cd.Ti is significantly correlated with T1.（P〈0.01）,and Be and Cr,Co and Cu,As,Ti,A1,Ni and V,and the correlation between them.At the same time,there is a correlation between Be and Cr,Co and Cu,As,Ti,A1,Ni and V,Be and Cu,T1.It is concluded that the content of some elements in drinking water in Datong is high,and most metal elements have a common source,which must be paid attention to.
