Standardized decay curves of acetic acid in a 1 m³—environmental test chamber under passive conditions with no air supply. Adsorbent media are representatively selected for each sorbent group. Occurred breakthrough after 28 h and 48 h is marked with an asterisk. PC1: pure activated carbon (unimpregnated coconut shells), IC7: charcoal impregnated with NaMnO₄, CC10, alkaline impregnated charcoal cloth, Z6: synthetic zeolite (type X crystal), SG2: silica gel (90% SiO₂; lithium chloride).
