Abstract
To enable high-speed analyses in the preparation of high-purity bismuth and bismuth oxide, we have developed an atomic absorption technique which ensures Ag, Cr, Cu, Fe, Mg, Mn, Ni, Pb, and Te detection limits in the range 2 × 10−7 to 2 × 10−5 wt %. The technique was used to assess the purity of bismuth and bismuth oxide in metal refining and oxidation steps.
