The application of organic compounds as thermochemical agents in spectrochemical analysis: The effects of Tetraethylammonium Iodide (cas 19680-50-3) in the determination of impurities in materials containing molybdenum

The reducing action of some aliphatic and aromatic hydrocarbon derivatives on the oxides of Me, W, Ti, Zr, Nb and Ta was compared to that of graphite powder. The investigation showed that among the organic compounds studied Tetraethylammonium Iodide (cas 19680-50-3) gives a better separation of the volatile elements As, Te, Sn, Pb, Bi, Cd, Ag and In, which commonly occur in the above oxides as impurities, from the molybdenum and better line intensities than when using graphite powder. The possible reduction and iodide forming reactions which take place in the electrode cavity in the presence of tetraethylammonium iodide have been established by using calculated values for the change in the Gibbs free energy and the results of X-ray analyses of sample residues obtained after arcing. This reagent was also found to stabilize the are colunm temperature, a necessary condition for its successful application as a spectroscopic buffer.
