Analytical .use of Arsenazo Iii Determination of Thorium, Zirconium, Uranium and Rare Earth Elements
The reagent arsenazo III (1,8-dihydroxynaphthalene-3,6-disulphonic acid-2,7-bis[(azo2)-phenylarsonic acid]) gives marked colour reactions with a number of elements. Anions affect the reaction only to a slight degree and it is possible to work at low pH values; the reaction is very sensitive and the compound can thus be used for the photometric determination of Th, Zr, I-If, U, rare earths, and ...
متن کاملRare Earth Elements Profile
Definitions and characteristics The rare earth elements (REE) (sometimes referred to as the rare earth metals) are a group of 17 chemically similar metallic elements, including the 15 lanthanides, scandium and yttrium. The lanthanides are elements spanning atomic numbers 57 (lanthanum, La) to 71 (lutetium, Lu) (Table 1). The lanthanides all occur in nature, although promethium, the rarest, only...
متن کاملDetermination of Rare Earth Elements in Products of Chadormalu Iron Ore Concentrator Plant (Iran) from Beneficiation Point of View
Different samples have been prepared from different products in Chadormalu iron ore concentrator plant: Low intensity magnetite separators concentrate (magnetite concentrate), reverse flotation tail (final hematite concentrate), flotation concentrate (apatite concentrate), final tail (L.I.M.S. tail + reverse flotation concentrate+ apatite flotation tail). The samples were used for rare eart...
متن کاملBiosorption of Uranium and Rare Earth Elements Using Biomass of Algae
In order to investigate the behavior of rare earth elements (REEs) and uranium (U) in marine organism, the concentrations of REEs and U in some brown algae samples taken on the coast of Niigata Prefecture were determined. In addition, laboratory model experiment to uptake these elements using living and dried algae (Undaria pinnatifida and Sargassum hemiphyllum) was also carried out to survey t...
متن کاملQuadrupole Interactions in Rare-earth Intermetallic Compounds
A survey of the role played by the one-ion magnetoelastic and two-ion quadrupolar interactions on the magnetic and elastic properties of the rare-earth intermetallic compounds is given. These couplings are present in numerous systems and manifest themselves through a great variety of effects. The study of the multipolar interactions concerning the 4f shell has known a great development about ra...
