GSC (stream sediments) AAS (Cd; air-acetylene flame using multi-acid total digestion)

Geological Survey of Canada, stream sediments; atomic absorption spectroscopy  (cadmium; air-acetylene)

General Methodology:

Determined by atomic absorption spectrophotometry after decomposition with a multi-acid total digestion.  A 500 mg sample was leached over a period of 4 hours using a 5 ml aliquot of HF-HCl-HNO3-HClO4 acid mixture (ratio 1:1:1:1).  A final solution of 5% HCl was made up to a volume of 20 ml. The element was atomized using an air-acetylene flame.
