摘要:

A new preconcentration procedure using inclusion of the metal dithiocarbamate complexes into a thin polystyrene film is developed. The method is applied for determination of Cd,Co,Cu,Fe,Ni,Pb and Zn in high purity KI,LINO3, BaCl2and Y2O3by arc-source AES. The relative standard deviation is 5-12% at concentration range 5.10−5-5.10−6%. The method permits the determination of 2.10−6% Pb and Cd, 5.10−6% Co,Cu,Fe,Ni,Zn.
