Abstract
The determination of cyanide (and other analysis) in the Li/SO2 matrix presents a number of analytical challenges. Cyanide ion (e.g. as LiCN), and other organic compounds, are formed as a result of decomposition of the electrolyte co-solvent, acetonitrile, in the Li/SO2 cell. The purpose of Phase 2 of this project was to develop interference-free methods for determining free cyanide-bearing compounds (e.g. - metal cyanides and thioicyanate ion) which might be found in discharged Li/SO2 cells. High performance liquid chromatographic (HPLC) and ion chromatographic (IC) techniques were employed to determine cyanide-bearing compounds and free cyanide ion respectively. This phase of the project also developed gas chromatographic techniques for determining various organic acetonitrile decomposition products.
