    • Abstract
  • OBJECTIVE A comprehensive understanding of the major and minor elements in different processed products of Pyrite， providing scientific basis for the clinical rational use of Pyrite. METHODS The determination method of 10 components including Fe，S，Si，Al and other major and minor components in different processed products of Pyrite by X-ray fluorescence spectrometry was established. RESULTS The detection limit of Fe，S，Mn，Si，Al，Ti，Ca，P，Zn and Pb was 13.37，36.92，7.56， 68， 29， 77.47， 12.46， 22.54， 21.64， 4.55， 3.24mg/kg. Determination of standard material composition of GBW (E) 070088 (iron ore) and GBW 07267 (pyrite) for 5 repetitions.The accuracy were 94%~107% and the RSD were 1.0%~10.1%. CONCLUSION The method can be used to determine the major and minor elements in different processed products of Pyrite， and it is accurate and convenient.
