| Abstract: | A method for determination of B,Ti,V,Zn,Cr,Mo and Cd in uranium dioxide and uranium uranic oxide powders by inductively coupled plasma mass spectrometry (ICP MS) is presented and described.The extraction chromatograph separation using CL TBP resin column to separate the matrix from trace elements is used for the samples.The analytes have been determined with the determination limits lower than 10 -9 g.g -1 ,and the relative standard deviations less than 15%,for concentrations greater than the determination limit.Comparison of analytical results between 14 laboratories shows that the method is highly accurate and reliable. |
