Abstract
The sorption of radium, barium and mixture of both elements has been studied in the zeolites 3A, 5A and Y. The ratio zeolite; solution was 100 mg: 10 cm3 and the pH was 3. Carrier-free radium was completely retained in all studied zeolites. When 0.0016 meq of barium/cm3 were added, the sorption of radium decreased in the zeolite 5A only and when 0.014 meq of barium/cm3, the radium sorption was reduced in all the studied zeolites. The sorption of barium was similar to that of radium. The amounts of sodium and calcium removed from the zeolites and the proton quantity fixed to them allowed us propose the ion exchange mechaniosm. The changes and ionic radii of the species exchanged did not play an important role. However, the location of the ions in the crystalline network of each zeolite is probably an important parameter for the exchange.
