Abstract
A study has been made of the polarographic behaviour of triphenylarsine oxide. It gives rise to a single cathodic wave in 0·1 M hydrochloric acid, which is considerably complicated by inhibition effects. These effects are removed by the addition of a surface-active agent, thus yielding a well formed diffusion controlled wave the height of which is proportional to concentration (up to 1 × 10–3M) and independent of pH. The current-potential relationships are discussed. On the basis of microcoulometric data and thin-layer chromatography the product of the electrode reaction has been shown to be triphenylarsine. Triphenylarsine oxide can be determined quantitatively in the presence of triphenylarsine by polarography.
