AB  - In this study, diffusion and adsorption behavior of volatile organiccompound of acetoneon building materials such as perliteplaster, thermal isolation plate plaster and machine plaster were investigated by using one-sided single pelletmoment technique. Experimental studies were conducted in a one-sided singlepellet Wicke Kallenbach type diffusion/adsorption cell under isobaricconditions. The amountof acetone in the gas phase was measured by GC technique. The zerothmoment analyses showed that the adsorption of acetone on all gypsum plastersused was found to be reversible. The results indicated that the adsorptiondegree of acetone on the thermal insulation plaster was the lowest value. Theacetone adsorption decreased with increasing temperature while the effectivediffusivities of acetone increased with increasing temperature in the gypsumplasters. Moreover, the studies revealed that the adsorption process wasphysical adsorption process and exothermic.
