Anotation

Description / Abstract: The principle of the method specified is dissolving a test portion in hydrochloric and nitric acids and dilution of the solution to a known volume, introducing a known volume of the solution into an electrothermal atomizer of an atomic absorption spectrometer, measuring the atomic absorption of the 217,6 nm spectral resonance line energy emitted by an antimony lamp. The method is applicable to antimony contents between 0,0005 % (m/m) and 0,010 % (m/m).
