[Questions_14]

Hi All,

I have been searching the web for days now, trying to find a way to selectively reduce Fe(III) to Fe(II) without reducing the uranium oxide (UO₂²⁺) present, and was hoping someone with more of a chemistry background could give me some advice on what to try/do.


Cheers

Their standard potentials are about 0.7V apart, so selecting correct reducing agent and correct conditions, so that formal potential in solution is somewhere in between should do the trick.

[Questions_14]

Borek, thanks for the reply. Are there any relatively cheap solutions that you would recommend trying? Generally operate in acidic conditions (pH of 2-3) if that is of any help?

You can try with I^-, in absence of air (in a closed container with negligible air in the space left and in the solution).

[Questions_14]

In the absence of air will not be possible, so any other ideas? I have found some information suggesting to use acidic ammonium nitrate as the reducing agent, however I would also like some others to try.


Cheers
