Bromine Reduction

Chemical Formula: Br2, BrO3, Br
Present as: anion

Bromine is a chemical element with symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Its properties are thus intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and Antoine Jérôme Balard (in 1826), its name was derived from the Ancient Greek βρῶμος “stench”, referencing its sharp and disagreeable smell.
Elemental bromine is very reactive and thus does not occur free in nature, but in colourless soluble crystalline mineral halide salts, analogous to table salt. While it is rather rare in the Earth’s crust, the high solubility of the bromide ion (Br−) has caused its accumulation in the oceans. Commercially the element is easily extracted from brine pools, mostly in the United States, Israel and China. The mass of bromine in the oceans is about one three-hundredth of that of chlorine.
Bromine is sparingly soluble in water. Organo bromine compounds are used as biocides, insecticides, and as a component of fire retardants.

Anion resin affinity for bromate increases with increasing size of the amine, therefore resins such as SIR-100 and SIR-110-HP have higher capacity for bromates than type I resins such as SBG1 or type II resins such as SBG2.

Bromide ions are quite soluble. Neutral bromide can be removed with strong base anion resins, acidic bromide solutions can also be removed by weakly basic anion resins such as WBMP.
