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.
