Abstract:An XRF fusion sefstromite sample was prepared with Li 2B 4O 7 as flux,and LiNO 3 as oxidant to prevent sulphur from volatilizing and LiBr as shed,and Mg,Al,Si,P,S,Ca,Ti,V,Mn and Fe were determined by XRF spectrometry.The interferences from line overlap and the inter-element absorption and enhancement effects are corrected by using the interfering curve method and the theoretical alpha coefficient.The results are in accord with certified values in standard reference materials.The RSD is from 0.27% to 5.24% (n=10).
Keywords:X-ray Fluorescence  Sefstromite  Fusion Method  Interfering Curve Method  Theoretical Alpha Coefficient
