[en] A method for the determination of trace tantalum in uranium compounds such as UO₂, U₃O₈, UF₆ or UF₄ is developed. The sample is converted to UO₂(NO₃)₂ and evaporated to near dryness, then add 0.5 ml 3 mol·1^-1 HNO₃-0.2 mol·1^-1 HF solution to dissolve the trace tantalum. After that the tantalum is separated from uranium with TBP levextrel resin chromatography and determined with horizontal ICP/AES. With a sample of 0.3 g, the determination limit of tantalum is 0.5 x 10^-6, the recovery is in the range of 88%-106%, the relative standard deviation RSD is ≤10%. This method is simple and rapid
