吉布提市自来水部分元素检测与分析

Detection and analysis of the elements in tap water from Djibouti city

目的为了保障亚丁湾护航补给饮用水的安全性,我们对亚丁湾护航补给点之一的吉布提市生活饮用水水质进行了元素检测。方法采集管网末梢水,利用电感耦合等离子体质谱仪(ICP-MS)检测水中Be、Na、Mg、Al、K、Ca、V、Cr、Fe、Mn、Co、Ni、Cu、Zn、As、Se、Mo、Ag、Cd、Sb、Ba、Tl、Pb、Th和U,共25种元素含量。结果除钠、铁和铊超标外,其余各项检测指标均合格。结论吉布提市市供自来水部分检测指标超过我国标准要求,该饮用水若未经处理暂不宜作为舰艇补给用水。

Objective To ensure the safety of drinking water supply for the escort fleet in the Gulf of Aden off Somalia,we measured the tap water from one of the supply points-Djibouti city. Methods The water pipe network peripheral was collected and 25 elements were detected including Be,Na,Mg,Al,K,Ca,V,Cr,Fe,Mn,Co,Ni,Cu,Zn,As,Se,Mo,Ag,Cd,Sb,Ba,Tl,Pb,Th and U by the Inductively coupled plasma mass spectrometry（ICP-MS）. Rusults All the detected metals and nonmetals were qualified except Na,Fe and Tl. Conclusion Some of the detected elements＇ concentrations in the sampled water from Djbouti city were above the Chinese drinking water standard.It is not suitable for supplying the water to the ships without proper treatment.
