Purpose

Bromine ions can enhance the inhibitory process of the cerebral cortex, generate sedation, and restore a balance between cortical excitation and inhibition. Oral administration is easy to absorb, and its distribution is the same as chloride ions. It is excreted by the kidneys, and sodium chloride can increase its excretion rate. Medically used as a sedative to treat symptoms such as neurasthenia and epilepsy. The photosensitive industry is used as a photosensitive emulsion. The wood industry is used as a fire retardant. In analytical chemistry, it is used for droplet analysis of copper. In addition, it is also used for slate printing, etc.
