Bondar Clegg (stream sediment) AAS (As; hydride evolution)
Bondar Clegg, stream sediment; atomic absorption spectroscopy (arsenic; hydride evolution)
A 1 gram sample was reacted with 3 ml concentrated HNO3 in a test-tube overnight at room temperature. After digestion, the test-tube was immersed in a hot water bath at room temperature and brought up to 90oC and held at this temperature for 30 minutes with periodic shaking. 1 ml concentrated HCl was added and heating was continued for another 90 minutes. The sample was then diluted to 20 ml with metal free water and mixed.
The element was determined by atomic absorption using a hydride evolution method wherein the hydride (AsH3 or SbH3) is evolved and passed through a heated quartz tube in the light path of an atomic absorption spectrophotometer. The method is described by Aslin (1976).
