Determination of Trace Impurity Elements in U_3O_8 by ICP/MS with Levextrel Resin Chromatography

A method for the determination of B,Ti,Cd,V,Cr, Zn, Mo,Sb,W and Bi in U3O8 by ICP/MS with TBP Chromatography is reported. The sample is dissolved in the solution of HNO3 and the uranium is separated by TBP levextrel resin chromatography. The trace elements retained in the aqueous phase are detected by ICP/MS. With a sample of 500mg, the detection limlts for all above elements reach down to 0. 0l X 10(-6)g/g, the average rccoveries are about 88~116% and the relative standard devlatlon is less than 14%.
