| titleOfInvention | Process for the chromatographic separation, especially of isotopes or ions with the aid of ion exchange resin coatings and suitable resins for the process |
| abstract | The invention relates to a separation process.nchromatography of chemical species using a resinnion exchange, used in particular to separate isotopesnuranium, boron and nitrogen.n n n Isotopic exchange takes place between an isotope ofnthe element fixed on an ion exchange resin and anothernisotope of the element present in a liquid phase in contactnwith the ion exchange resin.n n n According to the invention, for this exchange,nfilm resins formed from composite grains having aninert polymer core and at least one active film layerncomprising ion exchange groups. Layernfilm (3) can be arranged around an inert core (1)nmade for example of polyolefin. The film layer (9)ncan also line macropores (7) with a macroporous grain (5)nmade of inert polymer. We can also use the resins of thenFigure 1 to separate ions. |
