渭河咸阳段水质中重金属元素分析测定

Analysis and distribution of heavy metal of Weihe River at Xianyang Section

采用原子发射光谱分析法测定了渭河咸阳段的水质中Cd,Co,Cr,Cu,Fe,Mg,Mn,Ni,Pb,Zn等10余种金属元素的含量。实验结果表明,在渭河咸阳段水样中未检出Cd,Co,Cr,Fe,Ni,Pb,Zn等金属元素,Cu,Mg,Mn 3种元素的含量依次为0.822,15.20,0.032mg·L^(-1),均未超标,表明近年来随着政府对渭河沿岸的综合治理,附近工厂企业和人民群众环保意识的逐步增强,渭河水质污染得到了根本性的改善。

The Cd, Co, Cr, Cu, Fe, Mg, Mn,Zn, Ni and Pb and other metal elements of Weihe Water samples of Xianyang Section were determined by atomic emission spectrum . The experimental restllts showed that in the Weihe Water samples in Xianyang Section was not detected Cd,Co,Cr,Fe,Ni,Pb.The content of metal elements such as Cu,Mg,Mn elements were 0.822, 15.20,0.032mg·L^-1,there are no more than the limit value of standard- showed that in recent years with our comprehensive governance on the coast of Weihe, Nearby factory enterprises and improvement of the people environmental protection eonseiousness,Water pollution in Weihe has been funda- mentally improved.
