Method for separating metals by micellar ultrafiltration that can be used to process radioactive waste |
摘要 |
The present invention relates to a method for separating metals by micellar ultrafiltration, that can be used to process radioactive waste. This process consists of adding to the aqueous solution a complexing anionic surfactant having the formula: M+=cation, for example NA+m=1 or 2 R=aliphatic group of at least eight carbon atoms, and optionally a nonionic surfactant such as Triton X-100 or Brij 35 to produce micelles (10) in the solution, and subsequently of filtering the solution through an ultrafiltration membrane (3) to retain the previously formed micelles. |
