✦ Synopsis
hn underpotential-deposited cadmium layer formed on a gold electrode was used t o amperometrically cletcrmine I'(;O, in ;in aqueous medium. ?'his elccu-ode recluces nitrate anions in an aqueous solution. The reduction current Itrocluced can be related t o the proton c.oncentration. Thus, when dissolved (10, is present in ;I nitrate solution it alters the proton concentration, which ran then be measured am~teronietrically, Expcrimcntal investigation o f this system and :I Nafion coated gold electrode were Itoth carried out. Tile effect o f oxygen Itresent in the system is also cliscussecl.
