Description

The reduction of technetium, neptunium, and uranium was studied using a flow type electrolytic cell containing a carbon-fiber column electrode. Qualitative reduction of Np (VI) into Np (V) was confirmed at the potential of 0.3 V vs. Ag/AgCl in 3 mol·l-1 HNO3 solution. Quantitative reduction of U (VI) into U (IV) with co-existing Np and Tc was also confirmed at -0.3 V vs. Ag/AgCl in 3 mol·l-1 HNO3 solution. The reductive behavior of Tc still needs to be studied further. (author)
