  Halogens and Their CompoundsILO Encyclopaedia

  2 days ago · Bromine chlorine fluorine and iodine are chemical intermediates bleaching agents and disinfectants. Both bromine and chlorine are used in the textile industry for bleaching and shrink-proofing wool. Bromine is also used in gold mining extraction processes and in oil- and gas-well drilling.

  Chlorine and bromine atom ratios in the springtime Arctic

  1 The concentrations of a suite of halogenated volatile organic compounds (HVOCs) were measured near Barrow Alaska from January to April 2005. The HVOCs are produced from the reaction of bromine and chlorine atoms with ethene and propene. During periods of decreasing ozone concentration increases in the HVOC concentrations

  Bromine vs. Chlorine What to ChoosePool Research

  Compared to bromine chlorine requires daily maintenance for balance. Bromine has a greater efficiency over a wider pH range compared to chlorine. You shouldn t use bromine if levels are low or if bromine levels are too high. There is no UV degradation protection if using this compound. You ll need a spa cover to safeguard the water.
