OXIDATION OF AQUEOUS SOLUTION OF BROMIDE USING H2O2 , UV AND PEROXONE

Abstract

In this study , aqueous solutions of bromine were prepared with different concentrationranging from (0.025, 0.030, 0.035, 0.040, 0.045 to 0.050 N ) . At the beginning the oxidation wasdone using only Hydrogen peroxide then only ultraviolet radiation at 254nm wave length with differentperiods of time as for an interval of 10 minutes each hour. Consequently , the Oxidation was done byusing hydroen peroxide with ultraviolet radiation at the same wave length and at periodic time .Thefinal used method , peroxone which includes , ozone added to hydrogen peroxide at rate of 40 g/L to70 g/L for ozone was full fitted . Finally the production of each method for all concentrations andperiod was titrated with 0.1 N Sodium Thiosulfat to determine the concentration of Ion bromateBrO- 3 The results show that the ratio of the transformed ion bromide to ion Bromate the highest usinghydrogen peroxide with ultraviolet radiation . As such peroxone method and finally the methodfollowed where Hydrogen peroxide was specifically used .
