Polishing Materials for Electrodes in Electrochemical Experiments
Electrode Polishing and Testing Instructions
- Prepare electrode polishing materials. Remove the backing adhesive from the chamois polishing cloth and affix it to the electrode polishing plate. Pour polishing powder (1.0/0.5/0.3/0.05um) in reverse order onto the polishing cloth and moisten it with distilled water to form a paste.
- Place the electrode vertically on the polishing pad and polish by drawing "8" shapes, clockwise or counterclockwise circles, or horizontal strokes. It is important to ensure that the electrode is perpendicular to the polishing cloth. After polishing, rinse the electrode surface clean with distilled water.
- Choose cyclic voltammetry on the electrochemical workstation and test the electrode in a standard solution of potassium ferrocyanide. If the peak position difference is within 80mv, the electrode can be considered qualified.
- Take two clean beakers and place a dry ethanol (a) and a secondary deionized water (b) in them. Place the tested electrode in the two solutions in order (a, b) and clean it with ultrasonic waves for no more than 60 seconds. Remove the electrode and blow it dry before use.
- If the electrode needs modification, invert it on the electrode drying stand and apply drops.

Disc Electrode Polishing Steps
0.05um alumina powder is the most suitable for polishing disk-shaped electrodes. However, if scratches are found on the electrode, you need to use 1.0um, 0.3um, and 0.05um alumina powder in sequence to polish the electrode. After each polishing step, check the electrode surface, which should be flat and neat. Also, use the same alumina powder for polishing. If 1.0um alumina powder cannot remove scratches, you should first use 1200-grit metallographic sandpaper to polish and then use 0.05um alumina powder. The electrode surface will have a mirror-like luster.
Nylon polishing cloth and silk velvet cloth are used with 1.0um alumina powder, and the polishing flannel (coffee-colored) is prepared for 0.3um and 0.05um alumina powder. The back of the cloth has stickiness. Tear off the covering layer on the stickiness and press the polishing cloth tightly onto the dry and clean glass pad. Ensure that there are no bubbles between the glass pad and the polishing cloth. Before polishing, sprinkle a small amount of alumina powder on the polishing cloth and moisten it with distilled water. When polishing, hold the electrode vertically and steadily (not too hard). If the polishing cloth becomes dry, add distilled water and continue polishing.
Before using smaller alumina powder, thoroughly clean the electrode and wash your hands with water. If you accidentally sprinkle large powder on the small powder polishing cloth, you will not achieve the effect that small powder can achieve. Be careful when holding dry powder. Do not put large powder into small powder bottles. Do not exchange powder bottle caps at will. Use different spoons for different bottles when taking alumina powder from the bottle.
