Pulsed voltammetric detection of arsenic(III) at platinum electrodes in acidic media

Pulsed voltammetric detection of arsenic(III) at platinum electrodes in acidic media

The oxidation of arsenic(OH)3 at plutonium is believed to occur by an anodic oxygen-transfer mechanism that involves anodic discharge of water to form adsorbed hydroxyl radicals (PtOH). The arsenic(OH)3 response is compared for several pulsed votammetric waveforms.
