摘要：

A ZrNPs/Fe3O4/GO nanocomposite was successfully synthesized for the first time with an in-situ method, and its properties were defined by energy-dispersive X-ray spectroscopy, scanning electron microscopy, and powder-XRD techniques. Synthesized nanocomposite was then used as a modifier to prepare modified glassy carbon electrodes for the determination of nitrite ions in foodstuffs. Differential pulse voltammetry and cyclic voltammetry studies showed a high catalytic activity of the proposed nanocomposite in nitrite oxidation. In addition, the electrode showed a linear response between 3 and 76 & mu;M, a detection limit of 3 & mu;M, and high selectivity. The synthesized nanocomposite was stable for at least 9 months, and the resultant electrode had similar stability.
