Determination of Multi-elements in Ore Samples by Xray Fluorescence Spectrometry with Filter Paper Sample Preparation

A sample preparation method with filter paper for X-ray fluorescence spectrometric analysis of Fe, Cu, Pb, Zn in ores was achieved. The filter paper pre-treated with starch was used for absorbing analytes in solution and then dried under 50℃, shaped for XRF analysis with cobalt as internal standard. The method has been verified by analysis of Fe, Cu, Pb and Zn in National Standard Reference Materials. The results are in agreement with certified values with precision of <5%RSD (n=11). The method is simple, reliable and efficient.
