Abstract

Herein, a mesoporous Pr₆O₁₁ nanoparticle (NPs) has been prepared via a simple sonochemical process employing an eco-friendly capping agent, grape juice, and utilized for the development of a novel electrochemical sensor to measure carmoisine. Chronoamperometry, cyclic voltammetry (CV), and differential pulse voltammetry (DPV) have been used for the investigation of the electrochemical behavior of mesoporous Pr₆O₁₁/Ionic liquid/Carbon paste electrode (MP-Pr₆O₁₁/IL/CPE) in the presence of carmoisine. The oxidation behavior of carmoisine has been examined, and it has been discovered that there was a greater enhancing signal with the MP-Pr₆O₁₁/IL/CPE. A lowdetection limit of 12 nM in a linear range of 0.09-135 µM was achieved by the novel carmoisine sensor. Good selectivity, repeatability, stability, and reproducibility were all features of the newly constructed sensor. As a result, the suggested procedurewas appropriate for routine analysis and ought to serve as a viable option for analyzing food colorant.
