Bondar Clegg (stream sediments) AAS (8 + V; air-acetylene - using multi-acid total digestion)



Bondar Clegg, stream sediments; atomic absorption spectroscopy (Zn, Cu, Pb, Ni, Co, Ag, Mn, Fe, V; air-acetylene flame) using a multi-acid total digestion

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.

Background corrections were made to Ni, Co, Ag, Pb.
