“…The potentiality of Capillary Electrophoresis (CE) as a good analytical technique for analysis of radioactive elements starts to draw attentions of radiochemists since 1990s [7][8][9][10] because it has many advantages over the classical techniques mentioned above: 1) small sample volumes required. Hence, thirty nanolitres are enough for one injection, which is a significant advantage for radioactive samples.…”

Radiochimica Acta Print ISSN: 0033-8230 Volume: 93 | Issue: 5/2005 Cover date: 20050501 Page(s): 305-309 Abstract text A method for speciation of Tc(IV) species (TcCl62− and TcCl5(H2O)−) in chloride solutions, using capillary electrophoresis (CE) technique was developed. The proposed method has overcome the difficulties of unstable oxidation states analysis by shortening their travel time in the capillary. TcCl62− and TcCl5(H2O)− were thus separated without being hydrolyzed and polymerized, and their UV/Vis spectra were recorded. With a 1 M HCl/NaCl buffer solution (pH=1), the electrophoretic mobilities were determined as 5.47×10−4 cm2/Vs for TcCl62− and 2.13×10−4 cm2/Vs for TcCl5(H2O)− at 25 °C. The total analysis time for one run is 12 minutes

In this work an attempt is made to have a closer look at technetium species (TcX) induced by spinach plants, grown on TcO 4 containing nutrient solutions. To this end, size-exclusion chromatography (SEC) and reversed-phase ion-pair chromatography (RP-IPC) were used: The performance was established with model compounds, i.e., anionic Tc-DTPA and cationic Tc-cyclam, used as mimics for TcX. Under the conditions applied, the information retrieved from high performance RP-IPC was minimal due to strong interactions of the technetium species with the Nucleosil C18 stationary phase. However, in low-pressure SEC non-size effects allowed differentiation of TcX into two distinct classes of technetium compounds, i.e., TcX 1 and TcX 2. From retention behavior in SEC, it was possible to speculate on the chemical properties of these two technetium species.
