Abstract
In this study , aqueous solutions of bromine were prepared with different concentration
ranging from (0.025, 0.030, 0.035, 0.040, 0.045 to 0.050 N ) . At the beginning the oxidation was
done using only Hydrogen peroxide then only ultraviolet radiation at 254nm wave length with different
periods of time as for an interval of 10 minutes each hour. Consequently , the Oxidation was done by
using hydroen peroxide with ultraviolet radiation at the same wave length and at periodic time .The
final used method , peroxone which includes , ozone added to hydrogen peroxide at rate of 40 g/L to
70 g/L for ozone was full fitted . Finally the production of each method for all concentrations and
period was titrated with 0.1 N Sodium Thiosulfat to determine the concentration of Ion bromate
BrO- 3 The results show that the ratio of the transformed ion bromide to ion Bromate the highest using
hydrogen peroxide with ultraviolet radiation . As such peroxone method and finally the method
followed where Hydrogen peroxide was specifically used .
