In this research, electro-catalytic activity of paste electrode (PE) modified with Fe3O4-SWCNTs and 1Hexyl-3-methylimidazolium tetrafluoroborate (1H3MITFB) nanocomposites toward the oxidation of tert-butylhydroquine (TBHQ), was investigated. The results showed that Fe3O4SWCNTs/1H3MITFB/PE could improve the oxidation current of TBHQ up to about 3.65 times under the optimum condition. On the other hand, oxidation behavior of TBHQ was shown to have a linear relationship with pH of solution with a negative slope (55.2 mV/pH), confirming the presence of two electrons and two protons in redox reaction of this food additive. SW voltammograms of TBHQ at the surface of Fe3O4-SWCNTs/1H3MITFB/PE displayed a linear relationship in concentration range of 0.008 to 350 μM with the detection limit of 2.0 nM. The standard addition results showed that Fe3O4SWCNTs/1H3MITFB/PE could be used as a powerful analytical approach to determine TBHQ in food samples.
