Electroanalysis, Electrodeposition and Electrochemical Characterization of Ractopamine

摘要

We have first reported the modification of ractopamine electrodeposition films. In this paper, theelectrochemical oxidation of ractopamine in different pHs and conditions at the bare glassy carbonelectrode. The bare glassy carbon electrode also exhibits a promising enhanced electroanalytic activitytowards the oxidation of ractopamine. Different methods were used for the formation of poly- ractopamine films and the deposition on electrode. Cyclic voltammograms (CVs), Linear sweepvoltammetry (LSV) and Electrochemical impedance spectroscopy (EIS) are used for the determinationof ractopamine and the apparent diffusion coefficient values for these compounds at differentconcentration as it gives some information about the kinetics of charge transfer during the redoxreactions of these compounds. Finally, we have studied the surface morphology of the modifiedelectrode using atomic force microscopy (AFM), which revealed that ractopamine is coated on ITO.
