Electromigration of carrier-free radionuclides

Ion Mobilities of Trivalent f-Elements in Aqueous Electrolytes

“…Dependencies of this hitherto unknown effect on electrolyte overall ionic strength, temperature and ground electrolyte ions were studied in detail for americium(III) [13]. Fig.…”

“…The equation was treated by Computer minimization of the least squares function [21], varying the number n of the hydrogen cations. As a result, a first Order in H"^ concentration and a stoichiometric stability constant or \g ßf = 4.14(25) for ^-^lAm^^ and electrolyte parameters ß = 0.10(C104), 298.1 K, was calculated [13]. The results for the lanthanides are summarized in Table 2, varying the number of n in eq.…”

A device for on-line electromigration measurements of radioelements in free electrolytes

“…It was applied to the determination of limiting mobilities of microconcentrations of iodine and terbium ions [7]. This technique later on has been used to investigate the infinite ion mobility of 140 La 3ϩ [8] and 241 Am 3ϩ [13], the hydrolysis reactions of 205,206 Bi 3ϩ [9], 239 NpO 2 ϩ [10], 209Ϫ211 At ϩ [11], 169 Yb 3ϩ [12], 241 Am 3ϩ [13] and 249 Cf 3ϩ [14], the protonation of 131 IO 3 Ϫ [15], the effect of pH on the ion mobility of * Author for correspondence (E-mail : frank.roesch@uni-mainz.de).…”
