Type: article
Abstract: The objective of the present study was to evaluate the 137Cs binding capacity of natural and different monoionic forms of clinoptilolite in vitro, in a highly acid solution prepared to be similar to that within the stomach of swine. With the lower clinoptilolite concentration (100 mg) half of the initial 137Cs activity was sorbed during first 6 hours of incubation (48,9 %). Prolongation of the time of contact did not decrease solution activity. Using higher clinoptilolite concentrations (300 mg and 500 mg) the equilibrium of 137Cs ions was also established after 6 hours, but 75 % and 84 % of the initial 137Cs activity was sorbed. The similar efficiencies (84-85 %) found for natural and prepared forms of clinoptilolite indicated that there is no need to prepare mono-ionic forms (Na- and NH4 - clinoptilolite).
