摘要：
A process for removing undesirable material such as a radioactive contaminant from an underlying material. A solution containing fluoroboric acid and a material which affects oxidation potential (Eh) is contacted with the undesirable material to cause its removal. The material is removed from the fluoroboric acid solution by contacting the solution with a cation exchange resin and fluoroboric acid is regenerated in situ for continuous removal of undesirable material.
