Electrochemical sensing of phenolic compounds based on polymerized acyclic Schiff base modified,glassy carbon electrode

摘要

Acyclic Schiff base was synthesized by microwave irradiation method. It was characterized by UV-Visible, FT-IR, and NMR spectroscopy techniques, the electrochemistry of the Schiff base was studied by cyclic voltammetry. The synthesized. Schiff base was electrochemically polymerized, then used for electrochemical sensing of phenolic compounds. The polymerized Schiff base possesses high sensitivity towards the determination of phenolic compounds such as catechol, resorcinol and hydroquinone., The ability of polymerized Schiff base to form hydrogen bonding with phenolic compounds is one of the reasons for sensing of phenolic;compounds at slow potential. Polymerized acyclic Schiff base modified electrode shows better electrochemical sensing ability when compared to that of bare GCE.
