A green technique has been employed to synthesize the NiZnFe2O5 nanoparticles using papaya leaf extract. The X-ray diffraction investigated structural characteristics and crystalline size. morphology of synthesised nanoparticle is analysed by scanning electron microscopy. average diameter 47.93 nm, which was determined dynamic light scattering method. UV/Vis diffuse reflectance spectrum results revealed that NPs band gap 1.8 eV. It calculated Kubelka-Monk function energy dispersion spectroscopy analysis used identify synthesized nanoparticle's elements. electrochemical behaviour modified glassy carbon electrode (GCE) nd bare GCE studied detect ascorbic acid cyclic voltammetry differential pulse voltammetry. Compared unmodified GCE, exhibit excellent electrocatalytic activity towards AA oxidation, proved increase in peak current decrease potential. Electrochemical impedance suggests significantly enhance charge transfer rate. linear response on concentration obtained range 0.2-50 µM. detection limit found be 1.038 present work serves as a systematic benchmark assess sensing potential orange juice pharmaceuticals.
