A nanostructure voltammetric platform amplified with ionic liquid for determination of tert butylhydroxyanisole in the presence kojic acid
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 uM with detection limit 0.04 uM. 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.
