Abstract

This paper presents the results of studies on the strength and adsorption characteristics of granular activated charcoals of the brand ISQ DON GW4, С40/4 EXTRA KJ, and Norit RKJ4. The ultimate strength of samples was measured in different states: initial (H2O vapor saturation as a result of long-term storage), dehydrated, I2 vapor saturated and H2O + I2 vapor saturated. A significant (25…40%) decrease in the activated charcoal fracture stress due to the iodine vapor saturation, concerned with a Rehbinder effect, was observed. The degree of the adsorption decrease in the sorbent mechanical stability should be taken into account when selecting sorbents for filters of NPP air discharge purification systems (ventilation systems).
