- •
Se(IV) can be reduced to low soluble Se(0) upon interaction with Fe(II) or S(− II) in solution.
- •
Se(IV) is reductively immobilized by FeS in suspension at surface sulfide sites.
- •
In deep nuclear waste disposal sites the radionuclide 79Se(IV) will likely be reductively immobilized in the near field.
