Ferronickel -- Determination of trace-element content by electrothermal atomic absorption spectrometric method -- Part 3: Determination of antimony content
The principle of the method specified is dissolution of a test portion in nitric acid, measurement of the absorption of the resonance line energy from the spectrum of antimony in the test solution at a wavelength of 217,6 nm by an atomic absorption spectrometer fitted with a graphite furnace electrothermal atomizer, calibration by the standard additions method described in ISO 11438-1. Applies to antimony contents in the range of 1,0 g/t to 5,0 g/t in ferronickel.
