AB  - RATIONALE: Rare earth elements play an important role in identifying and indexing 
      the origin of historical and geological samples. In this work, a new approach for 
      the characterization of rare earth elements (REEs) in aqueous sample solutions 
      with high salinity is presented. METHODS: Prior to analysis by inductively 
      coupled plasma mass spectrometry (ICP-MS) the target analytes were separated from 
      interfering matrix constituents by the use of surface-functionalized 
      nanoparticles. Compared with common matrix separation techniques, such as 
      solid-phase extraction (SPE), the strength of the method lies in the combination 
      of an advanced extraction procedure with internal standard correction. Thus, 
      known limitations of SPE such as column clogging or incomplete analyte elution 
      could be completely circumvented. Furthermore, time-consuming approaches for 
      signal quantification such as matrix-matched calibration could be avoided since 
      the applied internal standard allows the correction of matrix-induced deviations 
      in sample extraction and ICP-MS analysis. RESULTS: With the developed procedure 
      detection limits <1 ng L(-1) could be achieved for all the investigated elements, 
      with satisfactory relative standard deviations (RSDs) of 3-26% for unspiked 
      samples and <1-2% for spiked samples. Results derived from recovery experiments 
      with spiked oil accumulation water samples confirmed the applicability of the 
      proposed procedure for the determination of REEs in highly saline sample 
      solutions. The procedure was successfully applied to the study of oil 
      accumulation water samples from different oil fields in Lower Austria. 
      CONCLUSIONS: A sample pretreatment procedure with subsequent ICP-MS analysis for 
      the accurate determination of REEs in aqueous sample solutions with high salinity 
      has been developed.
