Removal of gadolinium ions from solutions using granulated zeolites

The possibility of the use of granulated zeolites for the removal of gadolinium ions from solutions has been investigated. Measurements of Gd ion concentrations in solutions and of the distribution of Gd ions in column fillings (granulated zeolites), after passing the solution throught columns filled with various granulated zeolites (zeolite 4A, zeolite 13X and synthetic mordenite), have shown that Gd ions can be effectively removed from nearly neutral or acidic solutions using granulated mordenite. The influence of pH, column filling and the flow rate of the solution through the column, on the efficiency of Gd ions removal and on the distribution of Gd ions in the columns has been investigated. On the basis of the results obtained, the conditions for the most efficient removal of Gd ions from solutions have been obtained.
