原子荧光法测透析用水中砷硒锑汞

Atomic fluorescence measuring dialysis water arsenic selenium antimony and mercury

目的:建立透析用水中砷、硒、锑、汞四种微量元素的原子荧光分析法。方法:水中砷和锑加还原剂后同时测定;硒经硝酸高氯酸氧化后,再经盐酸还原后测定;汞直接加硝酸使酸度为5%后测定。结果:汞的检出限为0.024μg/L;硒的检出限为0.044μg/L;砷的检出限为0.011μg/L;锑的检出限为0.015μg/L。结论:本法用来测定透析用水中极其微量的砷、硒、锑、汞简便快速,且在双道原子荧光法仪中可同时进行砷和锑的检测。

Objective：To establish a method for detection of hemodialysis water arsenic,selenium,antimony and mercury.Methods：Arsenic and antimony in water were detectioned after added reductant,Selenium was detectioned by nitric acid and high chlorine acid oxidationed,Mercury was directly detectioned by adding acidity to 5%.Results：The detect limit for Mercury was 0.024 muon g/L,the detect limit for Selenium was 0.044 muon g/L,Arsenic detect limit for 0.011 muon g/L,Antimony detect limit to.015 muon g/L.Conclusion：This method wad simple and rapid for using to determine dialysis water in extremely trace of arsenic and selenium,antimony,mercury,and in double ways for atomic fluorescence analyzer can simultaneously arsenic and antimony detection
