摘  要:
研究了微波消解样品,试液用lCP-AES法同时测定样品中铅、镉、铬、汞、砷、硒的新方法。在选定的最佳条件下测铅、镉、铬、汞、砷、硒的检出限分别为0.0008、0.0007、0.0018、0.0028、0.0012、0.0046μg/L,回收率为94.5%~104.2%,RSD为1.4%~2.6%。本法准确、快速、简便,应用于水产品的测定结果满意。

摘  要:
The paper developed a newmethod of mi crowave sample degestion by ICP -AES to simultanuously deter-mine Pb,Cd,Cr,Hg,As and Se.Under th e optimumconditions,the detection limits of Pb,Cd,Cr,Hg and As were0.0008,0.0007,0.0018,0.0028,0.0012,0.0046μg /Lrespectively.The recoveries of the methodwere94.5%~104.2%,and RSD1.4%~2.6%.This method was accurate,quickly -accessible andconvenient.It was used in the determination of freshwater with th e result satisfactory.
