Abstract

In this research, a carbon paste electrode modified with CdO/CNTs nanocomposite and 1-Butyl-3-methylimidazolium hexafluorophosphate ionic liquid fabricated and was used for determination of butylated hydroxytoluene. CdO/CNTs synthesized by chemical precipitation method and characterized by XRD method. Under optimum condition, the peak currents of square wave voltammograms (SWV) of butylated hydroxytoluene increased linearly with its concentration in the ranges of 0.1–600 μM. The detection limit for butylated hydroxytoluene was 0.06 μM. The modified sensor has been successfully applied for the assay of butylated hydroxytoluene in food samples. In this research, a carbon paste electrode modified with CdO/CNTs nanocomposite and 1-Butyl-3-methylimidazolium hexafluorophosphate ionic liquid fabricated and was used for determination of butylated hydroxytoluene.
