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 phenanthrene-quinone, along with the pH insensitive ferrocene reference compound. The values of...

الملخص: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 phenanthrene-quinone, 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. © 2007 Wiley-VCH Verlag GmbH and Co. KGaA.
