The chemical reactions of the functional groups in polyurethane foams (PUF) have been studied by use of diffuse reflectance spectroscopy and infrared spectroscopy. It was found that the functional groups are highly reactive towards diazotization by sodium nitrite, azo coupling with 4-nitrophenyldiazonium tetrafluoroborate, oxidation by active chlorine, and condensation with formaldehyde, resulting in the formation of intensely colored products. Heterogeneous chemical reactions of PUF with these compounds in aqueous solution proceed rapidly at room temperature and at low solute concentrations. PUF do not undergo degradation as a result of chemical interactions. The linear response of the Kubelka-Munk function to analyte concentration makes it possible to recommend PUF as solid chromogenic reagents for the determination of nitrite, nitrate, and 1- and 2-naphthols.

Solid-phase matrices made of cellulose diacetate (CDA) as films and fibers were prepared. The CDA film matrices were found to be characterized by a negative value of the surface potential (-32 ± 2 mV) while the fibers had positive ones (+419 ± 1 mV). The possibility of using these matrices as sorption materials for luminescence analysis of polycyclic hydrocarbons in water-ethanol and micellar media is shown. Modification of such polymeric CDA matrices with surfactants of various natures improves their sorptive capacity and hydrocarbon recovery, and increases the sensitivity of luminescent analysis.

Cellulose diacetate (CDA) fibers and films, fibers of chitosan (CTS) of polycationic and polybasic forms were examined as matrices for solid-surface fluorescence (SSF) of hydrophilic fluorescent dyes : eosin Y and trypaflavine. CDA film and fiber ability to absorb trypaflavine was proved. The extraction degree and SSF signal of trypaflavine was higher for CDA film than fiber. The polybasic CTS was shown to have the highest sorption capacity (R = 95.5%) relative to eosin Y and to be the best matrix for its SSF signal. The obtained results can be used in the design of chemical sensors based on SSF measurement.
