Question
Will DPD chlorine tests detect Bromine?
Summary
Bromine as chlorine

Yes. Bromine is an interference in total chlorine analysis, bromine will show up as 1 mg Cl/L for every 2.25 mg Br/L actually present. When analyzing for free chlorine bromine can interfere but it will be significantly less and not easily quantified.
