XRFS Determination of Major and Minor Components in V and Ti-Bearing Magnetite with Sample Preparation by Fusion

Major and minor components in V and Ti-bearing magnetite were determined by XRFS. 0.200 0 g of sample was mixed with 6.000 g of a mixture of Li2B4O7 (a) and LiBO2 (b) with mixing ratio of ma to mb of 67 to 33, and fused at 1 050 ℃ with addition of 20 mg of NH4I as demoulding agent. Matrix effects were corrected by applying the theoratical α-coefficient. Calibration curves were prepared by using aset of standard samples. Detection limits of the 14 components were found in the range of 2-84 μg·g-1 .Values of RSD′s (n=12) found were less than 9%. In the analysis of a standard sample (BH 0101) by this method, results obtained were in consistency with the certified values.
