Embodiment 1
[0024] 1-Hexylpyridine hexafluorophosphate (HPPF 6 ) Modified carbon paste electrode preparation: weigh 1.6 g graphite powder and 0.8 g ionic liquid (HPPF 6 ) into a mortar and grind evenly, fill the ground mixture into a glass electrode tube with an inner diameter of 4 mm, insert a copper wire as a wire, and compact the solid mixture in the glass electrode tube to obtain ionic liquid modified Carbon paste electrode (CILE), the surface of the electrode is polished to a mirror surface before use.
Embodiment 2
[0026] Nafion / HRP / Co 3 o 4 - Preparation of GR / CILE: Prepare 15 mg / mL HRP and 0.5 mg / mL Co 3 o 4 -GR solution, take 0.5 mg / mL Co3 o 4 -GR solution 6 μL drop-coated on the electrode surface, after natural drying, apply 6 μL 15 mg / mL HRP solution on the electrode surface, after natural drying, apply 8 μL 0.5 % Nafion on the electrode surface to form a film to fix HRP, and the modified Electrode Nafion / HRP / Co 3 o 4 -GR / CILE.
Embodiment 3
[0028] figure 2 It is the ultraviolet absorption spectrum curve of HRP and HRP in HRP / Co3O4-GR composite material in PBS buffer solution of pH 3.0, and the experimental instrument used is TU-1901 double-beam ultraviolet-visible spectrophotometer. The Soret absorption band of HRP molecule in PBS is located at 403.0 nm (curve a), HRP and Co 3 o 4 - The Soret absorption band of the GR mixed solution in the TU-1901 double-beam UV-visible spectrophotometer is also at the same position (curve b), indicating that the HRP molecule is in the HRP / Co 3 o 4 -GR composites maintain their original structure without denaturation.
