“…Wavelength interference and selection for the determination of rare earth elements: Each element has several characteristic lines which can interfered with each other when there are many elements [11][12][13] , usually characteristic lines with high sensitivity and little interference are selected to measure, the selected wavelength of rare earth elements of this study were showed in Table- Impacts of acidity on the test: 0.5, 1.0, 1.5, 2.0, 3.0 mol L -1 hydrochloric acid were taken to make a series of concentration of standard solution and detected at the above working conditions. The results showed that when the concentration of hydrochloric acid within 1-3 mol L -1 the emission spectra intensity of rare earth elements is essentially the same and strong.…”

To investigate spectral interference of La, Ce, Nd, Sm, Eu, Gd, Tb, Yb, Lu and Y when detecting by inductively coupled plasma-atomic emission spectroscopy (ICP-AES), different types of soils were digested with a mixture of HF + HNO3 + HCl by microwave digestion instrument and precipitated twice to remove most of the matrix elements. The results showed a good method with high sensitivity, strong antiinterference ability to determine these elements simultaneously. The results to detect the soil standard reference materials (GSS-4, GSS-5) showed that measured values are all in range the standard value allowed and consistent with the standard value, indicating that the method is accurate and reliable. The detection limit of each element range from 0.2-38.2 µg L-1 , the relative standard deviations were between 0.8 and 3.2 %. This method has been successfully applied to determine the content of rare earth elements in soil samples from orchards in southern Jiangxi and the distribution of rare earth elements in the different types of soil were explored.

“…Standard analytical techniques such as inductively coupled plasma-mass spectrometry (ICP-MS) or ICP-optical emission spectrometry (OES)/atomic emission spectrometry (AES) are largely used for measuring the quantities of rare earth and the actinide that are produced in irradiated fuel. [2][3][4][5][6][7][8][9][10][11][12][13] It is impossible to analyze as-produced solutions that have very high radiological doses. Instead, these solutions must be diluted as high as a millionfold to be handled safely, and this dissolution contributes to analytical uncertainties.…”

This work extends a previous percentage level concentration study of the optical emission spectra for six rare earth elements, europium (Eu), gadolinium (Gd), lanthanum (La), praseodymium (Pr), neodymium (Nd), and samarium (Sm), along with the transition metal, yttrium (Y) using laser-induced breakdown spectroscopy (LIBS). The concentration of these six rare earth elements and yttrium has been attempted for the first time systematically down to parts per million (ppm) concentration levels ranging from 30 to 300 ppm. The authors have developed multivariate models for each element capable of predicting concentration with acceptable to excellent levels of accuracy. Additionally, partial least squares regression coefficients were used to identify key spectral features able to be used in this lower concentration regime. This study has demonstrated that it is conceivable to quantify the six rare earth elements along with yttrium at low concentrations in the parts per million levels.

“…There are numerous difficulties associated with undertaking the simultaneous analysis of actinides, rare earths, and other fission products, and extremely dense and complex spectral features result from the as-produced mixture. These difficulties are (i) experimental, (ii) operational, and (iii) safety related.The technique of choice for measuring the actinide and rare earth content in irradiated fuel is ICP-MS or ICP-OES/AES [30][31][32][33][34][35][36][37][38][39][40][41], but the challenge of analyzing concentrated solutions from fuel dissolution with very high radiological dose must first be addressed. This creates analytical uncertainties from large dilutions, up to a million-fold, which can be costly and time consuming and increase worker hazards in sample handling.…”

A study of the optical emission as a function of concentration of laser-ablated yttrium (Y) and of six rare earth elements, europium (Eu), gadolinium (Gd), lanthanum (La), praseodymium (Pr), neodymium (Nd), and samarium (Sm), hasbeen evaluated using the laser-induced breakdown spectroscopy (LIBS) technique. Statistical methodology using multivariate analysis has been used to obtain the sampling errors, coefficient of regression, calibration and crossvalidationof measurements as they relate to the LIBS analysis in graphite-matrix pellets that were doped with elements at severalconcentrations. Each element (in oxide form) was mixed in the graphite matrix in percentages ranging from 1% to 50% by weight and the LIBS spectra obtained for each composition as well as for pure oxide samples. Finally a single pellet was mixed with all the elements in equal oxide masses to determine if we can identify the elemental peaks in a mixed pellet. This dataset is relevant for future application to studies of fission product content and distribution in irradiated nuclear fuels. These results demonstrate that LIBS
