Direct current polarography in the presence of alternating voltages. I. Reversible systems

Abstract

The effect of a small sinusoidal A.C. voltage (c. 100 mV) on D.C. polarographic waves has been investigated. It has been found that the alternating current is rectified and the significance of this rectification is discussed for the case of reversibly discharged inorganic cations. A qualitative and quantitative treatment is given.
