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.
