Mineralization of organic matter takes place either by direct or indirect oxidation in an electrochemical oxidation reactor. As per literatures both occurs at same time. How can we find which one is more dominant (direct / indirect) in a particular electrode. Can OER Potential estimation can help in determining this?
Ali Raza Sir, The electrochemical series helps identify whether the electrode is oxidative. But how can we find whether direct oxidation or indirect oxidation reaction is dominant using the series since both reactions co-exist together?
Probably you need to block one route by adding some chemical agents. You need to eliminate the intermediate species that cause indirect oxidation. In general, it is easier to block HO*, electron mediated routes.
Well it depends on the potential that we applied. Positive potential gives oxidation reaction and negative potential gives reduction potential. If working electrode is in oxidation state then counter/ auxiliary electrode get reduced. It also depends on chemical behaviour of the electrolyte and assays that you studied.
