Removal of strontium ions from solutions using granulated zeolites

The ion-exchange process on columns filled with granulated zeolites is determined by several physico-chemical parameters. The influence of these parameters (zeolite type, concentration of exchangable ions in solution, temperature, flow rate, etc.) on the kinetics of ion-exchange process was studied by measuring the Sr2+ ions concentration in solution before and after passing through a column filled with various granulated zeolites (zeolite 13X, zeolite A synthetic mordenite). Using the experimental techniquea of radioactive labeling by 89Sr, the distribution of Sr ions in column fillings were also determined. From the results obtained, the optimal conditions for the most efficient removal of strontium ions from solutions, using granulated zeolites can be defined.
