Dear All,
On the occasion of Natalies's problem with the Zn reduction of her
water samples I would like to ask if someone has given any thought
(or a shot even) to reduce water samples using Mn?
Given the fact that its redox potential (-1.18 V) is smaller than
that of Zn (-0.7628 V) in acidic solutions it would appear to be the
more obvious candidate. What's more, is doesn't develop an "oxid-skin"
that renders its surface more or less inert.
I always wanted to try this one since I observed that Mn is capable
to reduce NO3- down to NH4+ in an aqueous suspension.
Any thoughts and/or comments?
Cheers,
Wolfram
