dc.description.abstract	New composite electrodes based on layer-by-layer modification with surfactants and carbon nanomaterials have been created and characterized with SEM and EIS. The electrodes have been applied for determination of natural phenolic antioxidants (morin, vanillin and syringaldehyde). Cationic (cetylpyridium bromide (CPB)), anionic (sodium dodecyl sulfate) and nonionic (Triton X100) surfactants have been investigated. The best voltammetric characteristics have been observed on CPB modified electrode. Differential pulse voltammetry has been applied for phenolic antioxidants quantification. The linear dynamic ranges for 0.1-100 and 100-750 μM with the limit of detection (LOD) of 28.9 nM are observed for morin. Vanillin calibration plots are linear in the range of 0.5-75 and 100-750 μM with LOD of 0.14 μM. Linear dynamic ranges for syringaldehyde are 0.75-10 and 10-750 ?M with LOD of 0.19 ?M. The approaches have been applied to morin and vanillin quantification in real samples.	ru_RU
