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

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.
