Redox reaction Yb(III) + e = Yb(II) in a molten eutectic mixture NaCl-2CsCl

Thermodynamic properties of thulium and ytterbium in fused NaCl–KCl–CsCl eutectic

“…Our obtained data are also compared with the literature for thulium and ytterbium in caesium chloride [17], and for ytterbium in fused NaCl-2CsCl eutectic [19], which are present in table 3. The average value of the radius of molten mixtures ðr R þ Þ was calculated by using the following equation [43]:…”

“…The concentration of Ln 2+ ions in the investigated melts was determined by volumetric method of analysis [19].…”

“…Also the study of Tm is interesting as it has exactly the same electrochemical behavior as Am. In addition, REE have similar chemical properties [6][7][8][9][10][11][12][13][14][15][16][17][18][19]37] to those of actinides [20][21][22][23][24][25][26][27][28][29][30] hence separation between these groups of elements is very difficult. For this reason, a good knowledge of the base thermodynamic properties of REE and An in the proposed separation media is very important.…”

An Electrochemical Study of Divalent Ytterbium Species in NaCl–KCl and NaCl–KCl–CsCl Based Melts

“…The electrochemical behavior of ytterbium species in fused alkali chlorides was studied in 3LiCl-2KCl, NaCl-KCl, 6NaCl-9KCl-5CsCl, NaCl-2CsCl and CsCl based melts employing stationary and transient electrochemical methods (electromotive force measurements, linear, cyclic and square wave voltammetry, and chronopotentiometry) (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20). Formal standard red-ox potentials (E* Yb(II)/Yb(III) ) and diffusion coefficients of the electroactive species were determined using the transient methods.…”
