In cyclic voltammetry, I ran a reduction blank from 0 to -1.6 V, in tetrabutylammonium perchlorate (TBAP) and dichloromethane, but the CV diagram shows a small wave at around -1.2 V, and I don't know if it is normal or abnormal, and if it is abnormal, what is the problem? The picture is below.
Dear Michal Hanko ,
Yes, I purged N2 gas 1 to 3 minutes everytime before measurments, but it still remains the same, I am really confused what the problem is.
If your working electrode is carbonous, it may due to the intercalation of perchlorate ions. Check it out in the literature.
The working electrode I used is Pt electrode,and it has plastic resin around it, I also change a new working electrode to see if it is the problem, but the result is still the same.
