Abstract
Differential pulse polarography was applied to analyze for phenylarsine oxide (PAO) in aqueous solutions at different pH values. Optimization of the instrumental artifacts resulted in a detection limit of 10 to the -8th power M PAO at pH 7.3, a relative standard deviation of 1.7%, and a maximum sensitivity of 450 microampere/mM PAO. The polarographic reduction of phenylarsine oxide was found to be pH dependent. Cyclic voltammetry and coulometry were used to characterize the electrode process.
