Development of an Ionic Liquid based-Fe3O4/Gr Nanocomposite for Sensitive Electrochemical Sensing and Monitoring of Vanillin in Food Products
Rapid electrochemical strategy-based sensor fabricated for measuring vanillin as an important additive compound in the food industry by combining iron oxide/graphene (Fe3O4/Gr) nanocomposite as a catalyst and 1-butyl-3-ethyl imidazolium chloride (1B3EICl) as an ionic liquid binder to make a modified carbon paste electrode (Fe3O4/Gr/1B3EICl/CPE). For optimization of the proposed sensor, some electrochemical parameters such as pH, scan rate, the ratio of Fe3O4/Gr, and 1B3EICl in the sensor matrix were investigated by differential pulse voltammetric method. The obtained results showed a wide dynamic range between 1.0 nM and 220 µM and detection limit of 0.5 nM to monitor vanillin using electrochemical signals. Finally, Fe3O4/Gr/1B3EICl/CPE was employed for analysis of real food samples and statistical analyses confirmed the efficiency of Fe3O4/Gr/1B3EICl/CPE for the determination of vanillin in real situations.
期刊介绍：
Topics in Catalysis publishes topical collections in all fields of catalysis which are composed only of invited articles from leading authors. The journal documents today’s emerging and critical trends in all branches of catalysis. Each themed issue is organized by renowned Guest Editors in collaboration with the Editors-in-Chief. Proposals for new topics are welcome and should be submitted directly to the Editors-in-Chief.
The publication of individual uninvited original research articles can be sent to our sister journal Catalysis Letters. This journal aims for rapid publication of high-impact original research articles in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
