Abstract
Polycyclic aromatic hydrocarbons (PAHs) are known ecotoxicants, the content of which in environmental objects requires constant monitoring. The development of new and improvement of existing methods for the analysis of PAHs is urgent. Luminescent methods are promising for these purposes, in particular, the solid-surface luminescence (SSL) method. In order to improve the analytical characteristics of the determination of PAHs by the SSL method, it is of considerable interest to study the possibilities of combining micellar and sorption concentration with the analysis of PAHs directly in the sorbent phase. The work is devoted to the development of a highly sensitive luminescent sensor system for the determination of PAHs using pyrene as an example by selecting the most effective matrix (cellulose, viscose, polypropylene and polyester) for sorption and observation of SSL, as well as modifying agents - surfactants: anionic - sodium dodecyl sulfate, cationic - cetyltrimethylammonium bromide and nonionic - Triton X-100. The maximum signal of TPL pyrene is observed on a viscose matrix when using a water-micellar solution of Triton X-100. The results obtained can be used to develop a highly sensitive method for monitoring the PAH content in various media.
