    Rare earth elements (REE) are important tools in geological studies. Accurate determination of REE concentrations can be affected in geological samples with low REE levels and/or high levels of interfering barium. Development of chemical separation methods allowing to isolate REE from other matrix components is a thorough approach to overcome this issue. In this study, a simple, RE resin-based separation method was developed and tested for a variety of sample solutions (mixed element solutions, shale, carbonate and granite). The method shows a good REE recovery and is efficient for the removal of matrix element, and notably Ba. The method is suitable for precise determination of the Eu contents in rock samples with high barium content.
