The radioactive 82Br was used as a tracer to study the bromide isotopic exchange reactions. The experiment was performed to study the effect of temperature, concentration of ionic solution, and amount of ion exchange resin on kinetics of isotopic exchange reactions. It was observed that under different experimental conditions, the amount of bromide ions exchanged and the initial rate of bromide ion exchange calculated for Duolite A 101D resins were higher than that for Duolite A 102D resins. It is expected that the same technique can be employed to assess the efficiency of various ion exchangers under different operating conditions. The probable mechanism of bromide isotopic exchange reaction was also predicted by comparing the specific reaction rate of rapid and slow exchange process.
