Abstract

In electrochemical sensor based on a carbon paste electrode modified with nanoparticles and Ionic liquid was studied. The sensor modified with graphenequantum dot and Ionic liquid nanoparticles was studied for Sunset yellow analysis and for this purpose, various parameters such as Ionic liquid ratio, the amount of Graphene-quantum dot nanoparticles and the pH were studied. The optimum content of 5% Graphene-quantum dot nanoparticles and 10% Ionic liquid and pH 6 was obtained. The best performance was observed in the modified carbon paste sensor of graphene-quantom dot nanoparticles and Ionic liquid. This sensor in optimal conditions with a linear amplitude of 3 nM to 150 μ M and a detection limit of 1 nM could be well used to determine the amount of Sunset yellow. The sensor designed to analyze the desired color was used in fruit juice samples and the results showed its high ability to analyze real samples.
