Abstract

Using a model solution of 12 aroma compounds, representative of microbial volatiles, 31 different adsorptive materials were investigated with regard to their solid phase extraction and desorption properties. Well known styrene—divinylbenzene‐based resins and alternative adsorbents including zeolites, β‐cyclodextrin and modified activated carbon were compared. Adsorption/desorption rates in aqueous solution were determined for each adsorbent. Isotherms and adsorption kinetics were determined for the most effective adsorbents.
