冰洲石中多元素的X射线荧光光谱测定

Determination of Multi-Elements in Iceland Spar by XRF

An X-ray fluorescence method for determination of CaO, Al_2O_3,SiO_2,Fe, P,Sr, Mn in iceland spar by the Rigaku 3080E3 Medel XRF spectrometer is described. A set of synthetic reference samples are prepared by diluting geochemical standard reference materials GSD with spectral pure CaCO_3. The powder-pressed pellet technique was used and the matrix correction was peformed by empirical coefficient methods. The precisions of the method can be compared with that of chemical analyeis and ICP-AES, The results are satisfactory. The analytical practice shows that this mathod is simple,accurate and practical.
