ellulose diacetate (CDA) and chitosan (CTS) were used in the design of sorptionmatrices for the sorption-flu-

orimetric analysis of polycyclic aromatic compounds (PAH) and heterocyclic compounds. The conditions

of making film matrices from CDA with high sorption capacity for organic fluorophores, in particular pyrene

were optimized. Various types of film matrices were made from CTS of the salt and basic forms. The morpho-

logical surface-energy, physicochemical and physicomechanical characteristics of our CDA and CTS matrices

in comparison with commercial CDA membranes, cellulose and chitosan containing sorption materials were

examined. The possibility of using CDA and CTS film matrices for solid-phase extraction and solid-surface flu-

orescence (SSF) of PAH, eosin Y and trypaflavine was investigated. The set of properties of our CDA film matrix

was found to cause high sorption and fluorescence of pyrene in the solid phase of the sorbent. Suitable condi-

tions for PAH sorption on the surface of CDA matrices were determined and a sorption-fluorimetric method to

analyze PAH in aqueous media was developed. The linear dependence of the SSF signal on the pyrene concen-

tration in the sorbate in the range 2×10-6 – 2×10-8 g/l of the substance was built. The possibility to determine

other PAH including the most toxic of them, benzo[a]pyrene, was proved. So, the SSF technique with the CDA

matrix allows analyzing PAH traces in environmental objects and may be used in environmental monitoring.

CTS matrices with adsorbed fluorescent dyes are shown as promising platforms for chemosensors. The devel-

oped polysaccharide matrices are characterized by relatively low cost, the ability of raw material reproduction

and waste biodegradation, which is important for their use in test systems and rapid analytic methods.
