A nanostructure voltammetric platform amplified with ionic liquid for determination of tert-butylhydroxyanisole in the presence kojic acid
TLDR
In this paper, the electrochemical behavior of tert-butylhydroxyanisole antioxidant was investigated at a surface of carbon paste electrode amplified with MgO nanoparticle and n-methyl-3-butylimidazolium bromide as conductive binder (CPE/MgO-NPs-/M3BIBr).Abstract:
The electrochemical behavior of tert-butylhydroxyanisole antioxidant was investigated at a surface of carbon paste electrode amplified with MgO nanoparticle and n-methyl-3-butylimidazolium bromide as conductive binder (CPE/MgO-NPs-/M3BIBr). The oxidation voltammogram of tert-butylhydroxyanisole was shown an irreversible signal with a diffusion controlled system. Using pH investigation data, we suggested a possible mechanism for electro-oxidation of tert-butylhydroxyanisole. The oxidation current varied linearly with tert-butylhydroxyanisole concentration in the range 0.1–700 µM with detection limit 0.04 µM. The CPE/MgO-NPs-/M3BIBr was resolved overlapping signal of tert-butylhydroxyanisole and kojic acid as two important antioxidants for the first time. The CPE/MgO-NPs-/M3BIBr was applied to the analysis of tert-butylhydroxyanisole in food samples such as edible oil and chilli sauce.read more
