Assessment of the adsorption strength of fragrances on zeolites via solid-phase extraction

ABSTRACT

Zeolites are porous materials, which have very interesting properties, very useful in physicochemistry, analytical, and industrial chemistry. In these works, solid-phase extraction technique was used for the description of adsorption/desorption properties of zeolite-like materials. Some natural and synthetic molecular sieves were tested. Three fragrance compounds: geraniol, menthol, and thymol were used as adsorbates. The obtained results indicate that the adsorption efficiency was higher for modified natural zeolites than for other materials. Chain compounds are strongly adsorbed by aromatic rings, so this property can be used in the preparation of fragrance materials.
