    Dysprosium Periodic Table of Elements and Chemistry

    Dysprosium was discovered in 1886 by French chemist Paul mile Lecoq de Boisbaudran when he separated dysprosium oxide from holmium oxide. Boisbaudran also discovered gallium in 1875 and isolated samarium for the first time in 1879 using fractional separation.. Boisbaudran developed an intricate and time consuming procedure for the separation of dysprosium.

    Etymology. Together with the two elements at the top of group 3, scandium and yttrium, the trivial name "rare earths" is sometimes used to describe all the lanthanides; a definition of rare earths including the group 3, lanthanide, and actinide elements is also occasionally seen, and rarely Sc + Y + lanthanides + thorium. [citation needed] The "earth" in the name "rare earths" arises from the

    The Separation of Am from Lanthanides by Purified Cyanex

    Abstract Separation factors of tracer amounts of Am from micro lanthanides (La, Ce, Pr, Nd, and Sm) by purified Cyanex 301 extraction in nitrate media have been determined SFAm/La 3500, SFAm/Ce,pr 1000, SFAm/Nd 1900, and SFAm/Sm 4500, with an average value >2300.

  • Process for separation of the lanthanides

    Process for separation of the lanthanides

    Aug 09, 1977Process for separation of the lanthanides. When the curves are obtained, as in FIG. 1, the process is applicable to all the rare earth elements. The speeds of extraction will vary depending on the rare earths so that the contact times will vary from 10 seconds to 100 minutes. Where long contact times are involved,

  • Liquidliquid extraction

    Liquidliquid extraction

    These are commonly used in industry for the processing of metals such as the lanthanides; because the separation factors between the lanthanides are so small many extraction stages are needed. In the multistage processes, the aqueous raffinate from one extraction unit is fed to the next unit as the aqueous feed, while the organic phase is moved in the opposite direction.

    Separation of rare earth elements. Lanthanides separation and preconcentration of high purity compounds is one of the most difficult problems in inorganic chemistry as it makes use of the subtle differences between the physicochemical properties of these elements and their compounds like solubility, basicity, volatility and possibility of occurrence with different oxidation numbers (Kowalczyk
