摘要：
The paper describes determination of antimony and bismuth in the metal-containing technogenic raw materials by atomic absorption spectrometry with electrothermal atomization (AAS with ETA). To improve the metrological characteristics, we used modification of the graphite furnace by complex compounds of precious metals and in some cases separation and concentration of antimony and bismuth by N,S-containing heterochain polymeric sorbents.
