3 PRINCIPLE OF THE METHOD
In acidic medium, the soaking liquid with thiourea A sample of arsenic, antimony reduced to trivalent arsenic, antimony, sodium trivalent arsenic, antimony and hydroboration
Volatile hydrides generated by an argon inlet atomizer, hollow cathode lamp at irradiation, emit fluorescence characteristic wavelength, the fluorescence intensity
Within a certain range with arsenic, antimony content is proportional to the standard series of quantitative comparison.
4 Reagents and materials
Unless otherwise indicated in the analysis using only analytical reagents, test water should be consistent with GB/T 6682 provisions of secondary water requirements.
4.1 hydrochloride (1.18g/mL). pure class distinctions.
4.2 glacial acetic acid (1.05g/mL). pure class distinctions.
