Fused Salt Polarography Using a Dropping Bismuth Cathode

Abstract
An apparatus is described which is suitable to study fused chlorides by the polarographic technique. Dropping bismuth is used in a way analogous to dropping mercury. Polarographic waves are shown for , , and in a eutectic melt at 450°C. The method serves as an analytical tool at high temperatures, besides yielding physicochemical information such as diffusion coefficients by application of the Ilkovic equation.
