“…Results showed higher concentrations of Cr and Pb in the upper sections of the sediment core indicating the impact of river input on the geochemical character of the dam sediment. Rare earth element ores were of interest to Zuzaan et al 189 in the development of an EDXRF technique for the determination of Ce, La, Nd and Pr using an instrument fitted with an 241 Am excitation source. Back into the field, Singh and Kumar 190 used WDXRF to analyse hand-panned mineral concentrates from riverine placer deposits around the Bastar Craton (Central India) for the elements Ce, Nb, Sn, Ta, Y.…”

“…Besides energy-dispersive X-ray analysis (EDXA) [ 11 ], X-ray fluorescence analysis (XRF) [ 12 , 13 ] and electrothermal atomic absorption spectrometry (ETAAS) [ 14 ], the most widely used determination methods for REEs appear to be neutron activation analysis (NAS) [ 15 , 16 ], inductively coupled plasma optical emission spectrometry (ICP-OES) [ 17 , 18 ] and ICP-mass spectrometry (ICP-MS) [ 19 , 20 ]. Although NAA is a sensitive technique that only needs small amounts of samples for analysis, this method suffers from time-consuming, requiring a neutron generation reactor and serious matrix interferences, which limit its extensive application in routine assays of REEs [ 9 ].…”

This work presents the long-term determination accuracy study of ICP-QMS for rare earth elements (REEs) in geological matrices. Following high-pressure closed acidic decomposition, REEs are measured repetitively across seven months by ICP-QMS. Under optimum experimental conditions (including spray chamber temperature, gas flow rate, sampling depth, etc.), the REE contents in geological standard materials from basic (basalt BCR-2 and BE-N) to intermediate (andesite AGV-2) and up to acidic (granite GSR-1) show good agreement with the certified values, giving relative errors below 10%. Here, the influence of two storage materials (perfluoroalkoxy PFA and polypropylene PP) on the long-term determination accuracy of REEs has also been monitored. It is found that the relative errors of REEs using a PFA container range from −6.6 to 6.3% (RSDs < 6.0%), while that using a PP container are within −4.0 to 3.9% (RSDs < 4.6%). By using PP material as a solution storage container, the accuracy of REEs quantification in a series of real geological samples are checked, showing the RSDs of less than 5.0%. This work first clarifies the long-term stability of REEs quantification by ICP-QMS covering two types of storage materials, confirming the reasonability of PP material as a daily storage container in terms of higher data precision and lower cost.

A novel magnetic Ce(III) ion-imprinted polymer (Ce(III)-MIIP), grafted on organic-inorganic hybrid monolithic vinyl functionalized Fe3O4 (Fe3O4@HM), was synthesized for the first time by using the surface ion imprinting technology, in which Ce(III) was used as the template ion and acrylamide as the functional monomer. After the synthesized nanocomposites were well characterized, some parameters such as pH, adsorption time, eluent type, elution time and eluent volume, which affects the efficiency of magnetic solid phase extraction (MSPE), were studied in the determination of Ce(III). Under the optimized experimental conditions, Ce(III)-MIIP nanoparticles were used as the MSPE matrix, followed by inductively coupled plasma mass spectrometry (ICP-MS) determination with excellent selectivity, strong anti-interference ability, low mass transfer resistance and high adsorption capacity. The limit of detection, enrichment factor and adsorption capacity were 0.008 μg•L −1 , 25 and 67.8 mg•g −1 , respectively. The protocol was validated by analyzing certified reference materials and spike recoveries of complex environmental and mineral samples with satisfactory results. The relative standard deviations for the real samples were 1.7%~7.0%. In view of the advantages of facile preparation, fast adsorption rate, excellent selectivity and high adsorption capacity to Ce(III), the hybrid monolith-assisted Ce(III)-MIIP-based MSPE-ICP-MS protocol is promising for the determination of cerium in real environmental and mineral samples.
