Abstract :
ZnO-CNTs and 1-butyl-3-methylimidazolium bromide (BMIB) ionic liquid were
used as amplifiers for modification of carbon paste electrode (CPE) as simple and powerful
electrochemical tool for analysis of tert-butylhydroquinone (TBHQ). The pH response on
electro-oxidation signal of TBHQ was investigated as effective factor on voltammetric
investigation. Under the optimized conditions, a linear dynamic rage 0.09–750 μmol L-1 was
detected for determination of TBHQ at surface of CPE/BMIB/ZnO-CNTs. The
CPE/BMIB/ZnO-CNTs was successfully used as electro-chemical food sensor for
determination of TBHQ in food samples.
