X-ray Fluorescence Spectrometric Determination of Major and Minor Elements in Dust Samples

摘要: 采用粉末压片-X射线荧光光谱法对灰尘样品中P、Ti、V、Ni、Cu、Zn、Ga、Rb、Sr、Nb、Cs、Ba、La、Hf、Zr、Pb、Al2O3、CaO、Fe2O3、K2O、MgO、Na2O、SiO2等主次量组分进行测定.探讨了谱线校正,使用经验系数法和康普顿散射线作内标校正基体效应.用国家一级标准物质进行验证,测定值与标准值相符.

Abstract: X-ray fluorescence spectrometric method with powdered pellet sample preparation for the determination of P, Ti, V, Ni, Cu, Zn, Ga, Rb, Sr, Nb, Cs, Ba, La, Hf, Zr, Pb, Al2O3, CaO, Fe2O3, K2O, MgO, Na2O, SiO2 in dust samples was developed. Compton scattering line was selected as internal standard and the empirical coefficient method was used for the matrix effect correction. The method has been applied to the determination of these elements in National Standard Reference Materials and the results are in agreement with certified values.
