摘要：

A simple and reliable ion chromatographic (IC) method for the simultaneous separation and quantification of Ti and Fe in U-Ti alloys is proposed. The developed method does not require pre-separation of matrix uranium and hence direct injection of the dissolved sample into IC is feasible. Separation was realized on a reversed phase column dynamically modified with ion interaction reagent (IIR). Suitability of three IIRs was evaluated and Camphor-10-sulphonic acid (CSA) was selected. Separation of Ti and Fe was achieved by mandelic acid whereas the strongly retained U(VI) was eluted with tartaric acid. The developed method was calibrated for Ti and Fe in presence of U(VI). The limit of detection (LOD) for Ti and Fe is 0.2 mu g/mL and 0.02 mu g/mL, respectively. The precision of measurements was better than 5 % (RSD) at 1 ppm of Ti and 0.2 ppm of Fe. The real samples were analysed with the developed method.
