  • Platinum as a Reference Electrode in Electrochemical

     · The usefulness of platinum as an electrochemical reference electrode was investigated. Well-known redox systems with one-electron single or multiple redox waves and two-electron multiple redox waves were used as test regimes. The effects on electrode performance of variables such as the solvent the physical state of the electrolyte and its temperature were investigated.
