Description
In a previous work, we have demonstrated that polyanions like polyacrylamidoglycolic acid (PAAG) and polyacrylamidomethylpropanesulfonic acid (PAMPS) are capable to complex UO22+ ions. Unless they are crosslinked, these polyanions/UO22+ complexes are soluble when submitted to dynamic leaching tests in a Soxhlet extractor. Considering the feasibility of a new process for the storage or for the concentration of low level activity liquid wastes (LLW), we had to strongly enhance the insolubility of these complexes. We have developed two original insolubilization ways, as compared to the crosslinking of the polymer
