中国南阳恐龙蛋化石中痕量稀土的LTLS测定

DETERMINATION OF TRACE RARE EARTH IN FOSSIL OF DINOSAURIAN EGG BY LASER THERMAL LENS SPECTROMETRY

本文报道了用激光热透镜法（ＬＴＬＳ）测定了恐龙蛋化石中的痕量稀土，用阴离子交换法分离和富集化石中的稀土，讨论了测量的条件和影响因素，得到了满意的测量结果，它不但为地质学恐龙蛋化石的研究提供了参考数据，也为岩矿中痕量稀土的测定提供了一种分析方法。

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.
