Özet
In this study, CuCo2O4-rGO nanostructures were synthesized by a one-pot electrochemical method on the surface of Pencil Graphite Electrode (PGE) for nitrite determination in past & imath;rma, a traditional meat product. The developed modified electrode was used to determine the amount of nitrite in past & imath;rma samples obtained from three different brands in the Turkish market. When the nitrite values obtained by the electrochemical method were compared with the spectrophotometric method, they showed 91.20 % to 100 % agreement. In addition, the physicochemical properties of past & imath;rma samples, such as pH, moisture, protein, fat, and ash, were analysed, and it was determined that pH and moisture values are critical parameters for product quality. These results show that the developed electrode provides a practical and sensitive method for nitrite sensing.
