摘要：The study specifies the characteristics of adsorbents for their subsequent use in adsorbers that are intended to trap aromatics from the juice vapour at the temperature and vacuum concentration of juices and extracts of plant materials. The paper presents our findings on the specific sorption capacities for aromatics of activated carbon BAC-A and porous polymers, such as polisorb-1, polisorb-10 and GC tenax. The experimental studies employed the dynamic method of gas chromatography with the use of the flame ionization detector. The trace curve of the adsorbate substance in the chromatogram allowed plotting adsorption isotherms and, consequently, calculating the specific capacities of adsorbents for camphor and isoamylol, as well as revealing that polysorb-1 is selective to isoamylol, whereas tenax and BAC-A – to camphor.The experiment findings have proved the applicability of this method for different adsorbents intended for adsorption of substances in the gas phase. The obtained data on the sorption capacities of the selected adsorbents are essential to calculate adsorption systems for trapping aromatics during the concentration of juices and extracts.
