Claessens, H.A. Wolterbeek, H.T. Faculty Applied Sciences Date 1996-03-01 Abstract The present paper addresses the potential use of capillary zone electrophoresis (CZE) as an analytical tool in 99- technetium speciation studies. In order to optimise sampling, storage and analytical procedures, the three marker compounds 99mTcO4-, 99mTc-DTPA and 99mTc-citrate were synthesised and used in test-measurements with CZE. The results underline the superior separation power of the CZE technique, and indicate good CZE performance for the stable 99mTcO4- and 99mTc-DTPA compounds. The data suggest that CZE may be used without problems for various Tc-compounds of intermediate mobilities. The specific data of 99mTc-citrate suggest that with this marker compound a threshold lability is reached for the use of CZE in plant Tc-speciation studies. This result means that CZE cannot be used in analyses of Tc-compounds which are less stable than Tc-citrate. Future CZE work will comprise the synthesis and use of Tc-markers of intermediate mobilities and stabilities; furthermore, effects of marker matrices and the plant matrix on CZE performance will be investigated.
