Bromine (Br) can usually be found as a bromide (Br‾) form contained in drinking water. Bromate (BrO3‾) formation often occurred during the ozonation process in the presence of Br‾. BrO3‾ is classified as a potential human carcinogen, so both the Br‾ and BrO3‾ concentrations must be strictly controlled before and after an ozone-based treatment procedure, respectively. This work reports on distance-based paper analytical devices (dPADs) that have been modified with silver hexagonal nanoprisms (AgNPrs) for highly sensitive and selectiv
