| Abstract: | Determination of trace rare earth in fossil of dinosaurian egg by LTLS (Laser thermal lens spectrometry) is presented in this paper.The trace rare earth in fossil of dinosaurian egg was separated and concentrated with ion exchange method.The measure conditions and effect factors are discussedian.The LTLS was applied to the determination of trace rare earth in fossil of dinosaurian egg with satisfactory results.It provides the reference data for the studies on the fossil of dinosaurian egg and an analytical method for the determination of rare earth in geochemical sample. |
