Spectroelectrochemistry in Melts: Applications to Molten Chloroaluminates

Abstract

Spectroelectrochemistry is an effective approach to studies of redox chemistry in solutions. uv-visible spectroelectrochemical studies in molten chloroaluminates (AlCl/sub 3/--NaCl mixtures) were initiated using a silicon vidicon rapid-scan spectrometer. Electrodes made from glassy carbon foam and metal grids are used in optically transparent thin layer cells. The solute species of interest are the oxidation products of sulfur and some of the Group IVB--VIB transition metal ions. The apparatus and the initial results are described.
