“…147 The detection limits ranged from 0.2 to 8 pg ml À1 and the recovery percentage from 95 to 100%. REE impurities were also determined in Sm matrix prior to ICP-MS detection by Zhang et al 148 Some analytes, such as La, Ce, Pr, Nd, Eu, Gd, Tb, Lu, and Y, could be measured without Sm matrix separation due to lack of interference affecting the analysis of these elements. On the other hand, Dy, Ho, Er, Tm, and Yb could be determined only after matrix separation.…”

An overview of publications focussed on the period since 2000 and outlining modern methods of sample preparation as well as advanced techniques for determination of rare earth elements (REE) in various matrices is presented in this paper. The review discusses the problems of REE determination in diverse samples i.e. from biological through environmental and geological to advanced materials. The preferable procedure of sample digestion and the most frequently applied methods of sample preparation for determination of trace elements are discussed in this paper. The case of direct analysis of samples for REE determination is also discussed. The review outlines determination of REE employing many techniques such as, inter alia, flame or graphite furnace atomic absorption spectrometry, atomic absorption with chemical vapor generation, X-ray fluorescence spectrometry, inductively coupled plasma optical emission spectrometry, inductively coupled plasma mass spectrometry and neutron activation analysis. This article summarizes and classifies materials in which rare earth elements are present, main places of their occurrence and the methods of their analysis.

The effectiveness of using materials based on rare earth elements (REE) largely depends on their impurity composition, which affects their structure and properties. Before the analytical quality control of REE-based materials and initial substances for their production, it is necessary to determine both macrocomponents and impurity elements with high sensitivity and accuracy. A complex of atomic emission and mass spectral analytical methods is often used for the determination of impurities in REE-based materials in the range from 10–5 to 5.0 wt.%. However, the analysis of such materials, even using these modern high-sensitivity methods is a difficult task due to spectral and matrix interferences. Therefore, different preliminary separation/concentration procedures are needed to determine both rare earth and other impurities. This article reviews publications is devoted to preconcentration methods for spectral and mass spectral analysis of REEbased materials and, in part, a number of other analytical techniques. It was shown that the most common approaches are liquid extraction and chromatography. Sorption, cloud-point extraction and coprecipitation are also used. There is no universal method. Each of the methods discussed in this article has its own advantages and limitations. The analytical completion of the method confirms the effectiveness of the selected separation/concentration method in each specific case.

“…Another group of authors also resorted to the use of an extraction chromatography separation of analytes from the matrix during the determination by ICP-MS of 14 REE in high purity samarium oxide. 149 Some analytes, e.g., Ce, Eu, Gd, La, Lu, Nd, Pr, Tb and Y could be determined in digests directly because there were no polyatomic interferences arising from the samarium. Other analytes (i.e., Dy, Er, Ho, Tm and Yb), had to undergo a matrix separation process using 2ethylhexyl hydrogenethylhexyl phosphonate extraction chromatography.…”
