Historio
Carl Jacob Löwig discovered bromine in 1825, while still a chemistry student at Heidelberg University, Germany.
Antoine Balard distilled the bromine from a solution of seaweed ash saturated with chlorine in 1824.
He finally published his results in 1826, providing evidence that the substance he had discovered was a new element.

Aplikoj
Bromine is used in making fumigants, flameproofing agents, water purification compounds, dyes, medicines and sanitizers.
Potassium bromide is used as a source of bromide ions for the manufacture of silver bromide for photographic film.
Bromine is also used to reduce mercury pollution from coal-fired power plants.
