In case of using carbon paste electrode for anodic voltammetric detn of analyte In alkaline medium strong peak strong peak appear at 1.32 V ?

23 September 2021 1 8K Report

THis peak appear also in blank, why this peak appear in alkaline meium

A strong increase of the curent (not a peak) is the evidente that water/HO- is oxidised at this potențial. The experiment is at the limit of the electrochemical window of the solvent.
