摘　　要：建立了一种使用等离子体发射光谱仪同时检测城市生活污水中的Cd、Cr、Cu、Pb、Ni以及Zn的方法。结果表明:运用该方法,Cd、Cr、Cu、Pb、Ni以及Zn共6种元素的检出限均能满足城市生活污水检测要求,6种元素的相对标准偏差均小于3%,标准曲线相关系数均≥0.9999,加标回收率在95%~103%之间,结果令人满意。本文介绍方法可快速、准确的测定城市生活污水中的重金属元素。A method for simultaneous detection of Cd,Cr,Cu,Pb,Ni and Zn in urban sewage by ICP-AES was established.The results showed that the detection limit of this method can meet the requirements of urban domestic sewage detection.The relative standard deviation of the six elements was less than 3%,the correlation coefficient of the standard curve was≥0.9999,and the recovery rate was between 95%and 103%.The results were satisfactory.The method can quickly and accurately determine the heavy metal elements in urban domestic sewage.
