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

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 PrimusⅡX射线荧光光谱仪对黏土样品中的A l2O3、S iO2、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%.

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.
