A Sensitive SiO۲@Fe۳O۴/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 SiO۲@Fe۳O۴/GO nanocomposite and ۱-methyl-۳-butylimidazolium bromide as a binder (SiO۲@Fe۳O۴/GO/CPILE) was designed. Cabergoline oxidation peak at SiO۲@Fe۳O۴/GO/CPILE surface was ۵۰۰ mV that was approximately ۲۰۰ 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 ۳.۰ times greater at SiO۲@Fe۳O۴/GO/CPILE surface in comparison to that of the CPE. The relevant linear response range and detection limit were determined as ۰.۰۷–۵۰۰.۰ and ۰.۰۱ μM, correspondingly. The adjusted electrode was successful in determining cabergoline within real specimens entailing adequate results.
