A method for the detection of "Tc by ICP-MS in environmental samples is proposed and explained in detail. This method combines the capabilities of anion exchange chromatographic TEVA-Spec' resin with prior isotope concentration using solvent extraction to Tn'butylphosphate. The problem that the excess of Mo in the solution analyzed by ICP-MS...

Thorium is a very sensitive element to matrix effects that appear at different stages of its preparation to be measured by alpha-particle spectrometry. These effects are particularly important for inorganic solid samples from environmental and industrial origin. To deal with this problem and to define the most suitable...

The aim of this paper is to carry out a deep study on the possibilities of using 99mTc from 99Mo-99mTc clinical isotope generators to trace the radiochemical separations for 99Tc measurements by ICP-MS. By appropriately de®ning a minimum detectable mass concentration (MDMC) for the mass spectrometer it is possible to conclude that such use is...

A big fertilizer industrial complex and a vast extension of phosphogypsum piles (12 km2), sited in the estuary formed by the Odiel and Tinto river mouths (southwest of Spain), are producing an unambiguous radioactive impact in their surrounding aquatic environment through radionuclides from the U-series. The levels and distribution of...

El objetivo de esta investigación ha sido analizar la valorización de un residuo generado en el proceso de pro-ducción de dióxido de titanio (vía sulfato), denominado yeso rojo, en la producción de cementos. Dicho residuo está compuesto fundamentalmente por sulfato de calcio dihidratado e hidróxidos de hierro. Para ello, ha sido necesaria la...
