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

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 .
