Antimony (Sb)

Atomic number: 51
Atomic weight: 121.757
Average concentration in ocean: 1.6 nmol/kg
Residence time: 5,700 years

Distribution in ocean
 Antimony a conservative distribution with a nearly constant vertical concentration profile and similar concentrations in both the Atlantic and Pacific (data).

Speciation
Antimony is present in seawater in the +V oxidation state as Sb(OH)6-.

Residence time
The antimony residence time is from Tracers in the Sea (Broecker, W. S. and Peng, T.-H., 1982.  Eldigo Press, Palisades, NY).  It was calculated from the global average river input.

Analysis
Antimony has been determined by neutron activation analysis.
