O-TOF-ICP-MS Analysis of Rare Earth Elements, Noble Elements, Uranium and Thorium in River-relating Species

Popis výsledku v původním jazyce

The determination of rare earth elements (REEs), Au, Pt, Ir, Pd, Th and U in various river species was performed by the orthogonal time-of-flight inductively coupled plasma mass spectrometry (o-TOF-ICP-MS). The method working conditions were optimised inorder to minimise the presence and possible spectral interferences of oxides. Ratios MO+/M+ as well as interference of light REE and Ba oxides/hydroxides with high REEs were evaluated and confirmed to be insignificant. Using the internal standard Re, non-spectral matrix effects (originally decreasing of intensities up to 15 %) were overcome and recoveries were found from 92 to 105 % for all matrices analysed. For solutions, limits of detection (3sigma) were 0.14 - 0.82 for REEs, Th, U and Y, 1.18 for La, 4.3 - 5.6 for Au, Pt, Ir and Pd 11 for Sc (all in ng L-1). The Principal component analysis was used for classification of samples according to their places of origin successfully. The o-TOF-ICP-MS was proved to be a very sensitive and
