Abstract

The method for determination of impurities Co,Mn,Mg,Cr,Si,Cu, Al and Ni in Be by ICP-AES is studied. The Be sample is dissolved by HCl,and is extracted by DBPA-benzoyl from HNO3 medium. The determined range of impurity elements is from 5. 0×10-4% to 0. 1%. The recovery is from 95% to 104% and the relative standard deviation is less than 10%(n = 6).
