摘要:

The sensitivity of antimony determination with atomic absorption spectrophotometry is enhanced to a large extent by introducing stibine gas into an argon-hydrogen flame. As a reducing agent, zinc tablet made from the zinc powder paste with water is successfully used for quantitative and rapid productions of stibine from antimony (III) solution. The sensitivity for 1% absorption of the signal is estimated to be about 0.004 ppm of antimony.
