水中溴的来源及处理
Source
Bromine is found in seawater and exists as the bromide ion at a level of about
65 mg/l. Bromine has been used in swimming pools and cooling towers for
disinfection, however use in drinking water is not recommended. Ethylene bromide
is used as an anti-knock additive in gasoline and methyl bromide is a soil
fumigant. Bromine is extremely reactive and corrosive, and will produce
irritation and burning to exposed tissues. Over 0.05 mg/1 in fresh water may
indicate the presence of industrial wastes, possibly from the use of pesticides
of biocides containing bromine Bromide is extensively used in the
pharrnaceutical industry, and occurs normally in blood in the range of 1.5 to 50
mg/l.
Treatment
Reverse Osmosis will remove 93 - 96% of the bromide from drinking water. Since
bromine is a disinfectant, it along with the disinfection by-products can also
be removed with Activated Carbon, Ultrafiltration, or Electrodialysis.
