Hey All,
I am using glassy carbon electrode in my experiment using Na2SO4 2.0 PH buffer as an electrolyte.
When i was doing the experiment, the overloading get started in my potentiostat due to which the bubbling of the electrode get started. I remove the electrodes washed it out but again the overloading started. After this when i used this electrode for th experiment after 1 day it was not giving any peak for CV . I think that the electrode surface has got destroyed.
Do you think the same?
If yes, then hoe can i recover its surface?
For to restore the surface of the electrode, you need to take 2000 abrasive paper and polish the electrode.
Hafiza Fatima Qayum Abdul Qayum The bubbling you observed is indicative of electrolysis occurring at the electrode, which can cause physical and chemical changes to its surface.
Hafiza Fatima Qayum Abdul Qayum Moderate damage can be repaired using electrochemical polishing techniques, while severe damage, such as deep cracks or chips, necessitates electrode replacement.
Set current limitations on potentiostats to avoid overloading, and clean the surface using electrochemical cleaning before the experiment to get rid of any contaminants.
Dear Hafiza Fatima Qayum Abdul Qayum
to recuperate the surface of your electrode you need to polish it with abrasive paper, degrease it in acetone and then electrochemically polish it.
