Título: | Determination of trace element concentrations stable lead, uranium and thorium isotope ratios by quadrupole-ICP-MS in NORM and NORM-polluted sample leachates |
Autor: | Mas, José Luis; Villa-Alfageme, María; Hurtado-Bermúdez, Santiago; García-Tenorio, R. CSIC ORCID | Fecha de publicación: | 2012 | Editor: | Elsevier | Citación: | Journal of Hazardous Materials 205-206: 198-207 (2012) | Resumen: | This work focuses on the monitoring of the potential pollution in scenarios that involve NORM-related industrial activities (environmental or in-door scenarios). The objective was to develop a method to determine extent and origin of the contamination, suitable for monitoring (i.e. simple, fast and economical) and avoiding the use of too many different instruments. It is presented a radiochemical method that allows the determination of trace element concentrations and 206Pb/207Pb/208Pb, 238U/234U and 232Th/230Th isotope ratios using a single sample aliquot and a single instrument (ICP-QMS). Eichrom UTEVA® extraction chromatography minicolumns were used to separate uranium and thorium in sample leachates. Independent ICP-MS determinations of uranium and thorium isotope ratios were carried out afterwards. Previously a small aliquot of the leachate was used for the determination of trace element concentrations and lead isotope ratios. Several radiochemical arrangements were tested to get maximum performances and simplicity of the method. The performances of the method were studied in terms of chemical yields of uranium and thorium and removal of the potentially interfering elements. The established method was applied to samples from a chemical industry and sediments collected in a NORM-polluted scenario. The results obtained from our method allowed us to infer not only the extent, but also the sources of the contamination in the area. | Versión del editor: | https://doi.org/10.1016/j.jhazmat.2011.12.058 | URI: | http://hdl.handle.net/10261/288038 | DOI: | 10.1016/j.jhazmat.2011.12.058 | ISSN: | 0304-3894 |
