“…To that end, the cell (placed just before the mass filter) is filled with a low pressure gas chosen for its chemical reactivity and selectivity towards the interfering ions. 4,[6][7][8] Using an ICP-MS equipped with a collision/reaction cell, we intend to investigate the chemical reactivity of Lanthanoids with gases in order to provide a way of eliminating isobaric interferences and get an efficient method applicable for the separation of lanthanoids in the gas phase. More generally, we are interested in measuring the isotopic compositions of Ln fission products, 9 actinoids (An) activation products and their decay products irradiated in nuclear fuels.…”

The reactivity of La + , Sm + , Eu + and Gd + with NH 3 (g) and ND 3 (g) is studied in the reaction cell of a quadrupole ICP-MS. For Ln + = La + and Gd + , the primary reaction channel is the formation of the LnNH + protonated nitride leading to H 2 elimination. The LnNH(NH 3) + 1-5 ammonia complexes of the Ln protonated nitride are further generated. Sm + and Eu + are much less reactive: the protonated nitride is not detected, and only small amounts of Ln(NH 3) 0-6 + are observed. DFT, MP2, CCSD(T) and CASSCF/CASPT2 calculations are used to explore the potential energy surfaces. For the La + and Gd + ions of f-block elements, the reaction pathways have three steps: first the formation of LnNH 3 + , then the isomerization to HLnNH 2 + , and finally the loss of H 2 associated with the formation of a Ln-N triple bond in the final product LnNH +. On the other hand, Sm + and Eu + are not able to form stable complexes. This was rationalized in terms of energy barriers for the chemical reactions and electronic promotion energies for these Ln + atoms.

“…Due to the high temperatures of the plasma, all molecular information is destroyed, and thus only elemental and/or isotopic species can be determined. Excellent reviews of the application of ICP to examine metals from soil environments can be found in the literature (Bacon et al, 1997; Barefoot, 1998; de la Guardia and Garrigues, 1998; Yamasaki, 2000).…”

The inability to determine metal species in soils hampers efforts to understand the mobility, bioavailability, and fate of contaminant metals in environmental systems, to assess health risks posed by them, and to develop methods to remediate metal contaminated sites. Fortunately, great strides have been made in the development of methods of species characterization and in their application to the analysis of particulates and mixtures of solid phases in physics, analytical chemistry, and materials science. This manuscript highlights a selection of the analytical methods available today offering the greatest promise, briefly describes the fundamental processes involved, examines their limitations, points to how they have been used in the environmental and geochemical literature, and offers some suggested research directions in the hope of stimulating further investigation into the application of these powerful tools to the problems outlined above.
