Chromium Schiff base complex as a electrocatalytic probe for the determination of hydroquinone

چکیده
— Salen type chromium Schiff base complex was synthesized by microwave irradiation. The complex was characterized by UV-visible, FT-IR spectroscopy and EPR spectroscopy. Electrochemical property of chromium complex was tested with the aid of cyclic voltammetry (CV). The synthesized chromium Schiff base complex was electrochemically polymerized and used for the detection of hydroquinone. Chromium metal ion has various oxidation states, (i.e., +3, +5 and +6) due to this nature it acts as a good oxidizing agent. The polymerized chromium Schiff base complex has better selectivity and sensitivity for hydroquinone determination. Hydroquinone (HQ) is an important organic compound that is widely used in many fields such as pharmaceutical, antioxidant, dye, photographic developers, lithography and cosmetic industries. It is toxic to human and difficult to degrade in the environment. So there must be an effective method for the determination of HQ. The polymerized Schiff base chromium complex modified GCE has better response when compared with the bare GCE. Therefore it can be a good electrochemical sensor for HQ determination.
