熔融制样X射线荧光光谱法测定海洋沉积物中主次痕量元素

Fusion sample X-ray fluorescence spectrometry major and minor trace elements in marine sediments

熔融片法制样,用PW2440 X射线荧光光谱仪测定海洋沉积物样品中Na、Mg、Al、Si、P、S、Cl、K、Ca、Ti、V、Cr、Mn、Fe、Ni、Cu、Zn、Ba、Ga、Y、Zr、La、Ce、Nb、Rb、Sr等26种组分,用国家海洋标准物质和人工合成标样作为校准样品,使用理论α系数和经验系数相结合的方法校正基体效应。方法用海洋沉积物国家一级标准物质验证,测定值与标准值吻合。

molten film sample preparation,with the PW2440 X-ray testing fluorescence spectrometer marine sediment samples Na,Mg,Al,Si,P,S,Cl,K,Ca,Ti,V,Cr,Mn,Fe,Ni,Cu,Zn,Ba,Ga,Y,Zr,La,Ce,Nb,Rb,Sr and other 26 kinds of components,with the national Oceanic standard materials and synthetic samples as a calibration standard,using theoretical and empirical coefficients α factor combination the matrix effect correction method.Methods using national marine sediment reference material verification,the measured value consistent with the standard value.
