Abstract
In this work, a new method for the synthesis of perbromate, based on the use of conductive-diamond electrodes is described. The procedure developed is able to produce significant amounts of perbromates by electrolyses of bromate solutions. Hydroxyl radicals seem to play a very important role in the process. For this reason, high current densities (that promotes its occurrence) and raw material concentrations around 0.1 M of bromates are required to obtain an efficient process. Temperature in the range 20–30 °C seems to be recommended to obtain good efficiencies of the electrosynthetic process although the explanation of this observation is still unclear.
