Description:
Mass spectrometry was used to detect transfer of deuterium from labeled reagents to arsines following hydride-generation reactions. The arsine gases liberated from the reactions of arsenite, arsenate, methylarsonic acid, and dimethylarsinic acid with HC1 and NaBD4 in H2O, or with DC1 and NaBH, in D2O, were examined. Differences in the mode of deuterium incorporation for the various arsines were detected. These results may help explain some of the observed variations in arsine-generation efficiency for various arsenic compounds present in environmental and biological samples.
