摘　　要：本研究采用ICP-MS法测定了玻璃水样品中的As、Cd、Mn、Cr、Cu、Co、Sb微量元素含量,建立了玻璃水样品处理及检测方法。结果表明,该方法得到的各元素标准曲线的线性相关系数在0.99982~0.99999之间,线性回归较好,检出限范围为0.008~0.078μg/L。加标回收率为95.5%~105.0%。相对标准偏差均在2.0%以下,测试精密度较好。测定了6种不同品牌的玻璃水样品中的7种微量元素的含量,除Mn、Cu外,其他元素含量差别不大。玻璃水挥发后,其中的微量元素富集在颗粒物中,对环境造成巨大危害,应引起相关部门重视。In this study,the contents of trace elements As,Cd,Mn,Cr,Cu,Co and Sb in glass cleaner samples were determined by ICP-MS method,and a method for treating and detecting glass cleaner samples was established.The results showed that the linear correlation coefficient of the standard curve of each element obtained by this method was 0.99982~0.99999,and the linear regression was good,with the detection limit range of 0.008~0.078μg/L.The recovery rate of standard addition was 95.5%~105.0%.The relative standard deviations were all below 2.0%,and the test precision was good.The contents of seven trace elements in six different brands of glass cleaner samples were determined.Except Mn and Cu,the contents of other elements had little difference.After the glass cleaner volatilized,the trace elements in it were enriched in particulate matter,which caused great harm to the environment and should be paid attention to by relevant departments.
