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 compo-nents including Fe,S,Si,Al and other major and minor components in different processed products of Pyrite by X-ray fluores-cence 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 prod-ucts of Pyrite,and it is accurate and convenient.
