Abstract
A simple pH probe is developed based upon the covalent chem. derivatization of carbon particles with anthraquinone. The amperometric response of electrodes constructed from this material is examd. and shown to produce a Nernstian linear response to pH from 1 to 9, over a range of temps. from 20 to 70°, consistent with a two-electron, two-proton electrochem. process.
