A Sensitive SiO2@Fe3O4/GO Nanocomposite Modified Ionic Liquid Carbon Paste Electrode for the Determination of Cabergoline

In this study, the initial report on determining cabergoline via nanostructure-adjusted ionic liquid carbon paste electrode with aqueous solutions is described. For this purpose, an original adjusted carbon paste electrode that uses SiO2@Fe3O4/GO nanocomposite and 1-methyl-3-butylimidazolium bromide as a binder (SiO2@Fe3O4/GO/CPILE) was designed. Cabergoline oxidation peak at SiO2@Fe3O4/GO/CPILE surface was 500 mV that was approximately 200 mV less compared to the oxidation potential pertaining to the CPE surface subjected to a similar state. Moreover, there was an increase in the peak current of approximately 3.0 times greater at SiO2@Fe3O4/GO/CPILE surface in comparison to that of the CPE. The relevant linear response range and detection limit were determined as 0.07-500.0 and 0.01 mu M, correspondingly. The adjusted electrode was successful in determining cabergoline within real specimens entailing adequate results.
