螯合树脂在线富集-火焰原子吸收光度法测定水中微量Cu、Pb、Zn、Cd

DETERMINATION OF TRACE Cu,Pb,Zn AND Cd BY CHELATING RESIN ON-LINE ENRICHMENT-FLAME ATOM SPECTROPHOTOMETRY

对螯合树脂在线富集，火焰原子吸收光度法进行了条件试验．试验证实方法对Cu、Ph、Zn、Cd4个元素检出浓度可达μg／L级，校准曲线线性、样品重现性及准确度可满足测定要求．

The conditions for chelating resin on-line enrichmet and flame atom spectrophotometry are tested.The experiment indi-cates that the chekout limits of Cu,Pb,Zn and Cd by this method can reach to ug/L,and the standard curve,the sampl re-covery and degree of preciseness can meet the requirements for determination.
