Metallic antimony is oxidized and evaporated in a first reaction chamber, and enters a second reaction chamber to react with plasma flows; the …
In addition antimony trioxide is possibly carcinogenic to humans (Sundar and Chakravarty, 2010). Very few sorption studies of Sb on natural sorbents have been reported to date (Filella et al., 2002b) although several studies have been conducted on adsorption of Sb onto pure mineral phases (Leuz et al., 2006).
Antimony can be oxidized easily by sulfur and the halogens when heated. When it is heated in air, it burns with a brilliant blue flame and gives off white fumes of the trioxide Sb 2 O 3. The trioxide of antimony is soluble in either acids or alkalies. The electronic structure of antimony closely resembles that of arsenic, having three half ...
