Kepák, S. Koutová, M. Kočiřík, A. Zikánová] Natural clinoptilolite has been used for the retention of RuO4 vapors and its sorption properties were determined under a dynamic regime. In the course of retention, dissocíation of RuO4 to RuO2 and O2 proceeds, which is probably in the first phase catalyzed by Fe2O3 contained in clinoptilolite and in the second phase, after the formation of RuO2, it is autocatalyzed by this oxide. The autocatalytic reaction, which is promoted by an increase of temperature, can theoretically proceed up to the complete clogging of the intergrain volume, which would give the RuO4 retaining capacities by several orders of magnitude higher than in the case of mere physical sorption. However, the exploitation of this capacity is, prior to the onset of the autocatalytic reaction, limited by the transient breakthrough of RuO4. Conditions were found under which this transient breakthrough is completely avoided. Akadùmiai Kiadó, 1992 Kepák F. Nuclear Research Institute, 250 68, Rež, (ČSFR) aut Koutová S.
