Abstract

In modern life, people often neglect to consider their eating habits. Antioxidants are primarily used as food additives due to their stability and low toxicity. TBHQ is a commonly used antioxidant in food products as an additive. Electrochemical sensors represent the most efficient method for detecting TBHQ. Porous Zr-MOF material has a large active surface area but low conductivity, which can be improved by forming a nanocomposite. The Zr MOF can be decorated onto f-CNF using a sonochemical method. A synergistic increase in current was observed in Zr-MOF/f-CNF modified electrode. The amperometric method was used to determine TBHQ in potato chips and biscuits. The results showed that the nanocomposite shows a wide linearity range (0.0025-2505.3 μM), stupendous LOD (0.14 nM), and conventional sensitivity (0.56 μAμM^-1 cm^-2). The recovery outcomes from the analysis with real samples confirm the practicality of the nanocomposite.
