Does anyone have any relevant expereince on the best way to remove antimony (Sb-125) from nuclear power plant liquid
waste?  Ion exchange has not been very effective.

of your particular antimony species is?  If you can measure
current in a conductivity bridge, while applying
increasing voltages, that would be the best answer.
Depending on the number you get, I may have a solution.

Dear Ed,
have a look at http://rzaix340.rz.uni-leipzig.de/~kind/rgseng.htm

This problem was solved using SGS-polymers.

Industrial application:
SGS-filters removes about 94% of antimony from a complex acid solution with
1 g/l of antimony.
Achieved concentration in eluate is 45-50 g/l and flow rate 1200 specific
volumes. Eluate is 15% solution of HCl.

These values are from literature. In most cases a better cleaning (up to
microgram per liter oer better) is possible.

Please feel free to Email me.
With regards
Tobias Kind
