Embodiment 1
[0027] The preparation method of polygold / acetylene black composite film modified glassy carbon electrode comprises the following steps:
[0028] 1) Ultrasonic dispersion of acetylene black into double distilled water to obtain acetylene black suspension; the content of acetylene black in the acetylene black suspension is 1mg / mL;
[0029] 2) The polished glassy carbon electrode with an effective diameter of 3 mm was ultrasonically cleaned in absolute ethanol and double-distilled water, and then rinsed with double-distilled water, and the suspension of acetylene black was dropped on the surface of the glassy carbon electrode, and placed in The acetylene black modified glassy carbon electrode ACET / GCE was obtained by drying under infrared light; the polished glassy carbon electrode was first polished by sandpaper and then polished to a mirror surface with 0.3 mm and 0.05 mm of alumina powder and suede in turn; each The dropwise amount of acetylene black suspension on the glassy ...
