Following salts of lanthanides
were used as standards: Samarium (III) chloride hexahydrate, Lanthanum (III) nitrate hexahydrate, Europium (III) nitrate hexahydrate, Terbium (III) nitrate hexahydrate, Holmium(III) nitrate hydrate, Thulium (III) nitrate hexahydrate, Lutetium (III) nitrate hexahydrate, Erbium (III) nitrate hexahydrate, Samarium (III) nitrate hexahydrate, Neodymium (III) nitrate hexahydrate, Gadolinium (III) nitrate hexahydrate, Dysprosium (III) nitrate pentahydrate, Ytterbium (III) nitrate pentahydrate, and Cerium (III) nitrate hexahydrate.
In the geochemistry of rare earth elements of the sedimentary processes, the differentiation in behavior and abnormal redistributions of lanthanides
within the REE composition are probably impossible without the participation of the oil and gas hydrocarbons determining the redox conditions of the environment, and never pass without the isomorphism of lanthanides
For the nuclei included in our study, all chains of lanthanides
begins as vibrational with R(4/2) near 2.
Although the lanthanides
are 'rare earths' some, like neodymium, actually occur more frequently than many more common metals.
Research works regardihg the obtaining of an electrode micro-alloyed with lanthanides
for electric arc clading.
In the same samples, TSH and 17-OHP were measured according to the instruction manuals of the dissociation-enhanced lanthanide
fluorescence immunoassay (DELFIA[R]) test kits Neonatal 17a-hydroxyprogesterone and Neonatal hTSH (PerkinElmer).
provide a theoretical description of spectroscopic properties of lanthanides
doped in various materials.
Synergistic solvent extraction and separation of lanthanides
using mixtures of 1-phenyl -3-methyl -4-benzoyl-pyrazol-5-one and aliquat 336: influence of the ammonium salt anion.
The technique uses compounds of a group of heavy metals called lanthanides
, which can be detected with the use of fluorescent light.
The emphasis of this announcement is on the ions, complexes, and organometallic compounds of the transition metals known as lanthanides
and actinides, post-transition metals, and metalloid elements.
Epsilon 5 excels at trace analysis of heavy elements such as As, Pb, Cd, and the lanthanides
in concentrations from 100% down to sub-ppm levels.
Experiments at low energy, below 8 keV, at the K edges of the early transition metals and the L edges of early lanthanides
have been more difficult to perform, because of absorption by the Be windows in the beam line and by the samples themselves.
