Sa. Pergantis et al., INVESTIGATION OF ARSINE-GENERATING REACTIONS USING DEUTERIUM-LABELED REAGENTS AND MASS-SPECTROMETRY, Talanta, 44(11), 1997, pp. 1941-1947
Mass spectrometry was used to detect transfer of deuterium from labele
d reagents to arsines following hydride-generation reactions. The arsi
ne gases liberated from the reactions of arsenite, arsenate, methylars
onic acid, and dimethylarsinic acid with HCl and NaBD4 in H2O, or with
DCl and NaBH4 in D2O, were examined. Differences in the mode of deute
rium incorporation for the various arsines were detected. These result
s may help explain some of the observed variations in arsine-generatio
n efficiency for various arsenic compounds present in environmental an
d biological samples. (C) 1997 Elsevier Science B.V.
