Introduction. Antimony (Sb, stibium) is a semimetallic element that belongs to the vanadium family (Group VA) of the periodic table and shares certain chemical and physical properties with lead, arsenic, and bismuth [1 ]. In nature, antimony is associated with sulfur as stibnite and occurs in ores with arsenic.Web
