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).
The sorption capacity for iodine vapors of samples of carbon fiber cloth materials 31-3, 31-6, 35-1, 35-2, and KIPT 16-00 obtained at NSC KIPT, carbon fiber cloth materials of the Saut and Busofit brands and active granular carbons ISQ-3, SKT-3, and DGF-2 has been studied. The sorption capacity of carbon fiber cloth materials of series 31-6 and KIPT 16-00 is ~ 30% higher in comparison with Saut fiber cloth and ~ 4 times higher than the characteristics of active granular carbons SKT-3 and DGF-2 it has been shown.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
