| Abstract: | A procedure for the measurement of the isotopic composition of Fe in rradiated Na2/FeNO/CN/5/.2H2O samples by SSMS is described. Decomposition with K2S2O7, followed by extraction of Fe was necessary to eliminate interferences in the mass spectra. A study of the remaining interferences showed that they were of organic origin from the residual MIBK used for the extraction. The order of magnitude of the55Fe/58Fe and59Fe/58Fe ratios was calculated.SSMS: spark source mass spectrometry. |
