Triple Component Carbon Epoxy pH Probe

A pH probe based on a carbon‐epoxy electrode design is discussed. The electrode consists of three redox active components within a carbon epoxy matrix. These are the pH sensitive species anthraquinone and phenanthrenequinone, along with the pH insensitive ferrocene reference compound. The values of...

Zusammenfassung:A pH probe based on a carbon‐epoxy electrode design is discussed. The electrode consists of three redox active components within a carbon epoxy matrix. These are the pH sensitive species anthraquinone and phenanthrenequinone, along with the pH insensitive ferrocene reference compound. The values of the peak potentials when combined are shown to shift by 120 mV/pH unit at 25 °C with respect to the ferrocene reference potential.
