Polyaniline-modified cobalt oxide nano-flowers for efficient electrochemical detection of nitrite.

ABSTRACT: In this work, a modified electrode containing a conducting polymer (polyaniline) with Co₂O₃ nanoflowers (NF) was constructed for efficient nitrite detection. The as-prepared GC/Pani/Co₂O₃-NF was characterized using various analytical techniques, including Infrared spectroscopy (IR), ultraviolet-visible spectroscopy (UV-vis), scanning electron microscopy (SEM), X-ray diffraction (XRD), atomic force microscopy (AFM), and thermal analysis (TGA/DTA) to ascertain the Co₂O₃'s chemical composition and surface morphology. Furthermore, the electrode's activity toward nitrite detection was studied in a broad pH range, from 2 to 10. The linear detection range and limit were found using the amperometry approach. The GC/Pani/Co₂
