Abstract

A free-liquid electromigration method is described for studying the occurrence of technetium in ground water. Cells made of pyrex glass, teflon and plexiglas were examined for absorption, diffusion, and electroosmotic effects. Average mobilities of 5.38 x 10**-4 in oxic conditions and 5.15 x 10**-4 c**2s**-1 V**-1 in anoxic conditions were obtained for the pertechnetate ion in groundwater (ionic strength 3 x 1**-3 M) at 24 degrees C. The effective diffusion coefficient of this ion was calculated as 1.37 x 10**-5 cm**2s**-1 for oxic conditions.
