| Abstract: | Influence of different methods for dissolving samples on determination thorium and tantalum in uranium dioxide core are studied.According to correct iron to boron spectral line interfere, application of two methods(Inter-Element Correction and Multi-Component Spectral Fitting)in correcting spectral line interfere are discussed.The influence of temperature and acidity of solution on separating uranium and impurity elements by CL-TBP chromatography are examined.Improving instrument detection precision by adding internal standard element and the method of eliminating ho- ron element memory effect are also investigated. |
