| Research Abstract |
A new control technology for halogen oxide anions such as bromate ion were developed. This technology is based on the electrochemical reduction. Cyclic voltammetry of several electrode materials revealed that cupper was suitable to cathodic material for bromate reduction. Then treatment of tap water using a two-compartment electrolytic flow cell with a cupper mesh cathode was performed at the optimal condition. As the result, DC power consumption for removal of bromate ion from 100 to 10 μg/L was estimated to be 0.64 kWh/m3 and treatment time required was only 7.7 minutes, which was much shorter than biological activated carbon based techniques. Thus this method was thought to be a promising technology for bromate control.
