Abstract：The sample was prepared by fusion method using lithium tetraborate-lithium carbonate as flux and ammonium iodide as releasing agent. The analysis method of silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, manganese oxide, vanadium pentoxide, chromium oxide, phosphorus, titanium dioxide and total iron in vanadium slag, vanadium slag clinker and vanadium tailings by X-ray fluorescence spectrometry(XRF) was established. The results showed that the sample fusion results were best under the following conditions: the sample mass was 0.25 g; the dilution ratio (mSample∶mFlux) was 1∶20; the dosage of release agent was 20 mg. The empirical coefficient method was used for the correction of matrix effect and the spectral overlapping interference. The relative standard deviation (RSD, n=10) of components in vanadium slag samples was between 0.10% and 1.9%. The detection limits were between 35 μg/g and 460 μg/g. The proposed method was verified using the certified reference materials and actual samples. The found results were consistent with the certified values and those of actual samples obtained by wet method. The proposed method could meet the requirements of routine analysis.
