10 Dec Where can you find bromine?
Bromine is never naturally found in its elemental form but rather in inorganic compounds, also known as bromides, and in natural organo-bromine compounds1. These brominated compounds are found in soils, salts, air and seawater. 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.
