摘要

FIELD: chemistry.;SUBSTANCE: composition having GCR activity for the determination of polyaromatic heterocyclic sulfur-containing compounds (PHSC) in hydrocarbon products is a chemotropic gel containing a polymer matrix with silver nanoparticles of anisotropic shape with a size of 10-90 nm and particles of graphene oxide with a size of 1-2 mcm. A process for the preparation of this composition comprises the synthesis of silver oxide, dissolution of the resulting suspension in an aqueous ammonia solution, mixing the resulting solution with graphene oxide, sequentially introducing silver nitrate and a reducing agent to produce silver nanoparticles in a suspension of 10-90 nm in size and introducing a polymer powder for the suspension transition into a hemotropic gel. A planar solid-state optical sensor includes a film having a thickness of up to 5 mcm obtained from a composition having a GCR-activity and containing on the surface π-acceptor compound. The PHSC analysis method includes applying a liquid sample to the planar solid-state optical sensor with the test compound.;EFFECT: creation of planar optical sensors that allow using the method of giant Raman spectroscopy with high sensitivity, high selectivity, a wide range of detectable concentrations and high reproducibility and precision.;24 cl, 6 tbl, 17 dwg
