What is Bromine?

Bromine, an ubiquitous element found in the environment (soils, salts, sea water, air), is a highly volatile reddish-brown liquid in its elemental form (Br2) at room temperature. It is though never naturally found in its elemental form, but in compounds with other substances, known as bromides. Bromides are used as the raw material to produce commercial brominated products.

 


Antoine Ballard, the French chemist who discovered Bromine

Two forms of brominated products are abundant in nature: bromide salts and organobromine compounds, which are produced by many types of marine organisms. The most recoverable form of bromine is from soluble salts found in seawater, salt lakes, inland seas, and brine wells. Sea water contains bromine in about 65 parts per million (ppm) but bromine is found in much higher concentrations (2,500 to 10,000 ppm) in inland seas and brine wells.

Globally, most bromine is produced from salt brines in the United Stated and China, from the Dead Sea and Japan. Bromine is also present in certain rocks and in the earth's crust.
