GSC colorimetry: Sb



Geological Survey of Canada, colorimetry using “brilliant green”, to determine Sb, hydrochloric acid dissolution

General Methodology:

Antimony is extracted by hydrochloric acid after the sample has been heated with ammonium chloride.  The complex formed between antimony and “brilliant green” is extracted with toluene and the blue colour obtained is compared with a series of standards similarly prepared.
