Ten years back I tried the same, but I found it was not possible to recycle
used Zn shot for further use for the D/H analysis. Perhaps it has to do with
surface of the Zn, as the reaction takes place on the surface of the Zn
If you see the surface of the Zn grains before the reaction it is like a
I have tried to show the clean surface with the help of SEM photographs

But after the reaction the recycled Zn surface is smooth all the pours are
and inspite of cleaning with nitric acid it remains like a solid block. It
looks like we
have to live with it.

We have accumulated a lot used Zinc shot in our lab in deuterium isotope
analyses. I wonder if it's possible to recycle the used Zn shot for further
use in D/H measurement. I tried washing with HNO3 to remove the oxides and
vacuum-drying, but it didn't work.
Your suggestions, method of treatment or references are all welcome.
Thank you for your attention.
