Method for separating technetium from a nitric solution

The invention concerns a method for separating technetium from a nitric solution by cathodic electrodeposition of said technetium using electrolysis. The invention is characterised in that the technetium is denitrified and its pH is adjusted to a value of about 5.5 to 7.5 before electrolysis. The el...

Zusammenfassung:	The invention concerns a method for separating technetium from a nitric solution by cathodic electrodeposition of said technetium using electrolysis. The invention is characterised in that the technetium is denitrified and its pH is adjusted to a value of about 5.5 to 7.5 before electrolysis. The electrolysis is carried out in galvanostatic operating conditions, and the cathode potential is about -1.36 V/ENH to -1.16 V/ENH. The ratio of the cathode surface (S) and the volume of the technetium solution to be electrolysed can be about 0.25 to 0.50 cm-1.
