Electrochemical Polymerization of Guaiacol in Organic Solvents and Analytical Performance of the Poly (Guaiacol) Modified Electrode Towards Phenol Antioxidants
Year: 2025
Type: article
Abstract: The electrochemical polymerization of guaiacol was studied in different organic solvents and significant electrode blocking was observed in dichloromethane and microscopic studies verified the formation of coherent deposit on platinum electrode. In acetonitrile the insulating deposit formation proceeded above 20 mM monomer concentration. The differences between acetic acid and ethyl acetate allowed us to make estimations for composition of their binary solvent mixtures utilizing the shape of curves related to guaiacol electropolymerization but only in a narrow range. Guaiacol was not therefore reliable in solvent composition estimations. Poly(guaiacol) modified platinum macroelectrode was assessed in analyses in solutions prepared with organic solvents due to its apolar nature. The analytical performance of the modified electrode was tested in case of butylhydroxyanisole and butylhydroxytoluene. Linear sweep voltammetry was applied under stirred conditions and diminished noise of stirring was experienced compared with the bare electrode but with lower sensitivity.
