摘要

A method for direct determination of Cu, Pb, Zn, S, Mg and As in copper sulphide concentrates by Axios PW4400 wavelength dispersive X-ray fluorescence spectrometer using lithium metaborate-lithium tetraborate fusion sample preparation method has been developed. Some parameters affecting the sample preparation such as flux, glassing reagent and pre-oxidation condition were studied. The matrix effect was corrected by combination of the theoretical alpha coefficients and experienced coefficients. The precision of the method is better than 3.0%RSD (n=12).
