Summary, etc. |
Maghemite (γ-Fe<sub>2</sub>O<sub>3</sub>) nanoparticles have been synthesized using co-precipitation method followed by chemically induced transition process. As prepared nanoparticles have been analyzed by X-ray diffraction, Raman and FTIR spectroscopies which reveal the γ-Fe<sub>2</sub>O<sub>3 </sub>phase. These γ-Fe<sub>2</sub>O<sub>3</sub> nanoparticles have been used to modify the glassy carbon electrode (GCE) to form nano γ-Fe<sub>2</sub>O<sub>3</sub> modified GC electrode for electrochemical sensing of acetaminophen (C<sub>6</sub>H<sub>9</sub>NO<sub>2</sub>) using potential controlled cyclic voltammetric (CV) technique. The obtained modified electrode shows an excellent electrocatalytic ability to sense acetaminophen in 0.1 M KCl supporting electrolyte. In addition, a significant enhancement in anodic peak current has been observed using nano γ-Fe<sub>2</sub>O<sub>3</sub> modified GC electrode than the bare electrode. The CV plots reveal that redox peaks have been linearly co-related to the acetaminophen concentration in the range of 0.031 mM to 1 mM with sensitivity ~30.78 µA/mM. |
