Abstract

In Brazil and in the world to search for alternative fuels has become increasingly important and biodiesel fuel is considered a totally viable when compared to fossil fuels, due to its low emission of greenhouse gases. However its low oxidation stability is directly reflected in their quality, so synthetic antioxidants are the main compounds that have been used in the preservation of biodiesel against these oxidative processes.The determination of these compounds typically employs sophisticated techniques which require costly and in many cases use of toxic solvents. A viable alternative for the determination of antioxidants in biodiesel with low detection limits and less costly is the use of electroanalytical sensors. As a result, this project aims at the development of electrochemical sensor for determining the antioxidant butylated hydroxytoluene (BHT) and tert-butyl hydroquinone (TBHQ) in samples of soybean biodiesel microemulsion based on glassy carbon electrodes modified with pentacyanonitrosylferrate carbon nanotubes containing nickel and copper.
