Abstract
The electrochemical behavior of the four arsenic species, As(III), As(V), monomethylarsonic acid (MMA), and dimethylarsinic acid (DMA), was examined at a gold disk electrode. The As(III) species in solution was determined by anodic stripping voltammetry. The experimental conditions that were established for this determination were employed for the determination of As(III) that was formed by the reduction of As(V) by glutathione. The presence of an Arsenic(III)-glutathione complex in solution was established by cyclic voltammetry.
