Study on the determination of V, Cr, Fe, Ti, Zr in ilmenite mineral by using X-ray fluorescence

The content of some elements such as V, Cr, Fe, Ti, Zr in ilmenite mineral was determined directly and quantitatively by using X-ray fluorescence spectrometry. The important parameters, which influenced with the analytical results such as Cu, Mo secondary fluorescence target, excited high voltage, tube current of X-ray generator, and sample preparation procedure for ilmenite mineral samples was investigated and setting optimized. The data acquisition and processing were done by a Energy Dispersive Spectrometer (ED-XRF) Compact generator CK-5 with Molybdenum anode, Cu secondary target, the GENIE-2000 and Win Axil software. Based on the measurement of standard samples using fundamental parameter mode in Win Axil software, the content of V, Cr, Fe, Ti, Zr in samples was calculated accurately. The precision and accuracy of quantitative analysis was tested by references material standard and comparative analysis with different chemical analytical methods. The analytical procedures were set-up and applied for the determination of V, Cr, Fe, Ti, Zr in Vietnam exporting ilmenite mineral with high precision and accuracy. (author)
