THE ESTIMATION BY PAPER CHROMATOGRAPHYnOF NITRO- AND NITRATO-COMPLEXES OF NITROSYLRUTHENIUMnIN PROCESS SOLUTIONS

摘要

The parameters affecting the separation of nitrosylruthenium nitrato-and nitro-complexes by paper chromatography have been studied, and a comparatively labile species is postulated to account for some anomalous behaviour. The former paper chromatographic method for the estimation of the proportions of nitro- and nitrato-complexes has been found to be sensitive to the precise conditions used. For process solutions containing uranyl nitrate, a modified procedure is given which uses the results from elution with dibutyl cellosolve. This method indicates a higher proportion of nitro-complexes in process solutions than was found previously.
