Abstract
Physicochemical properties of commercial medical CO2 sorbents Amsorb Plus, Draeger 800, Draeger free, Loflosorb, Sodasorb, Sofnolime, Spherasorb, Ventisorb, as well as of the Russian adsorbent HPI were studied to determine the chemical compositions, textural characteristics, effective protection time with respect to CO2; crushing and attrition resistance of granular sorbents were measured using the SHELL SMS-1471 and ASTM D 4058 96 procedures. The best performance (a high CO2 capacitance, strength) was observed with Draeger 800. The obtained data on operating properties of commercial sorbents and recommendations can be useful for medicine, rescue works, as well as for scientific and production activities when cleaning air mixtures from carbon dioxide is necessary.
