X射线荧光光谱法测定黏土中的主次组分

Simultaneous Determination of Major and Minor Components in Clay Samples by XRF Spectrometry

摘要: 采用熔融玻璃片制样，选用标准样品，以经验α系数和散射线内标法校正元素谱线重叠干扰和基体效应，使用ZSX Primus Ⅱ X射线荧光光谱仪对黏土样品中的Al₂O₃、SiO₂、Fe₂O₃、CaO、MgO、K₂O、Na₂O、MnO、P₂O₅、TiO₂、Cu、Cr等组分进行测定，分析结果与标准值和化学值相吻合，12次测定的相对标准偏差小于10%.

Abstract: An X-Ray fluorescence spectrometric method(using a ZSX Primus Ⅱ XRF spectrometor) with fusion sample preparation technique has been developed for the determination of Al₂O₃、SiO₂、Fe₂O₃、CaO、MgO、K₂O、Na₂O、MnO、P₂O₅、TiO₂、Cu、Cr in clay. The matrix effect was corrected by experiential α coefficient and scattered line as the internal standard. The results are in agreement with certified values with precision of less than 10% RSD.
